Dallas Cowboys quarterback Tony Romo and wide receiver Dez Bryant connected for their 50th career touchdown in regular-season play, breaking the old franchise record for a quarterback-receiver combo set by Troy Aikman and Michael Irvin (49), per Elias Sports Bureau (h/t ESPN Stats & Info).

Facing a 2nd-and-goal from the Miami 16-yard line on the first play of the fourth quarter, Romo perfectly lofted a pass to a double-covered Bryant, who managed to gain separation from both of the defenders watching him.

The score broke a 14-14 tie in a game the Cowboys would eventually win 24-14 to put an end to their seven-game losing streak.

It was Romo's fifth passing touchdown of the season and Bryant's second receiving score of the year, as the former has only played three games and the latter just five.

The Golden State Warriors will look to set a new NBA record in Tuesday's game against the Los Angeles Lakers, with a shot to become the first team in league history to win each of its first 16 games in a season, per ESPN Stats & Info.

Sitting at 15-0 so far, the Warriors are currently tied with the 1948-49 Washington Capitols and 1993-94 Houston Rockets for the best start to a season in NBA history, per ESPN Stats & Info.

Of course, the team Golden State will most frequently be compared to is the 1995-96 Chicago Bulls, a squad that went 72-10 in Michael Jordan's first full season back with the team, following an extended break to play minor league baseball.

The Warriors obviously still have a long way to go, but ESPN's Basketball Power Index gives them a 27 percent chance to reach 70 wins and a 10 percent chance to reach 72 wins, not to mention a 95 percent chance to win Tuesday's game against a struggling in-state rival.

San Antonio Spurs forward Tim Duncan recorded six assists and six blocks in Wednesday's 109-98 win over the Denver Nuggets, making him the oldest player in NBA history to have five or more assists and five or more blocks in the same regular-season game, per Elias Sports Bureau (via ESPN.com).

Duncan accomplished the feat at the age of 39 years and 207 days, breaking the record previously set by Hall of Famer Kareem Abdul-Jabbar (38 years, 273 days) on Jan. 14, 1986.

With the Spurs entering Wednesday's game as a heavy favorite, Duncan didn't seem likely to set any records, as there was a good chance his minutes would be limited.

However, Nuggets rookie center Nikola Jokic had other plans, with his 23 points and 12 rebounds keeping Denver in the game, which allowed Duncan to log 28 minutes.

Minnesota Timberwolves center Karl-Anthony Towns had 21 points, 12 rebounds and six blocks in Wednesday's 104-101 overtime loss to the Orlando Magic, becoming the second-youngest player in the last 30 years to record 20 or more points, 10 or more rebounds and five or more blocks in a single game, per ESPN Stats & Info.

Unsurprisingly, the youngest player to accomplish the feat was New Orleans Pelicans forward Anthony Davis, who had his first of 16 such performances at the age of 19 years and 243 days, putting up 23 points, 11 rebounds and five blocks against the Charlotte Bobcats in just the third appearance of his career, per Basketball-Reference.com's play index.

Towns, the first overall pick in the 2015 NBA draft, hit the 20-10-5 mark in his 12th career appearance, at the age of 20 years and three days.

He is now averaging 15.8 points, 10.7 rebounds, 2.4 blocks, 0.9 assists and 0.5 steals over 29.6 minutes per game, making him the clear favorite for NBA Rookie of the Year honors, even with other members of the 2015-16 rookie class also off to strong starts.

Houston Rockets guard James Harden posted a historic stat line in Wednesday's 108-103 overtime win over the Portland Trail Blazers, becoming the first player since steals were first recorded in 1973 to have 45 points, 11 assists, eight rebounds and five steals in one game, per NBA.com/stats.

Known primarily for his scoring and secondarily for his distributing skills, Harden had a rare across-the-board performance in Wednesday's game, though the five steals likely overstate his true impact on the defensive end.

More impressive was his scoring prowess in an otherwise ugly game, as the 26-year-old accounted for 42 percent of his team's points, in large part because he got to the free-throw line 20 times and made 19 of those attempts.

Harden actually wasn't all that efficient from the field, making just 11 of his 29 field-goal attempts (38 percent) and four of his 15 three-point attempts (27 percent).

The Philadelphia 76ers committed 31 turnovers in Wednesday's 112-85 loss to the Indiana Pacers, marking the most turnovers by one team in a regular-season NBA game since the Golden State Warriors also had 31 in a contest during the 2000-01 season, per Sportsnet Stats.

It was a true team effort for Philadelphia, as each of the 11 players that entered the game had at least one turnover, with nine players committing multiple infractions.

The worst offender was rookie point guard T.J. McConnell, who had five turnovers in just 20 minutes, though he did lead the team in points (16) and collected six rebounds.

On the other side of the game, five different Pacers had multiple steals, with star forward Paul George (four) leading the way.

New York Knicks forward/center Kristaps Porzingis had 29 points and 11 rebounds in Tuesday's 102-94 win over the Charlotte Hornets, becoming the youngest player in franchise history to record 25 or more points and 10 or more rebounds in the same game, per Elias Sports Bureau (via ESPN Stats & Info).

Selected fourth overall in the 2015 NBA draft, the 20-year-old Latvian was widely viewed as a long-term project, with few outside of the Knicks organization counting on a significant year-one impact.

Even among an impressive rookie class, the skinny 7'3" big man has made a particularly strong impression, averaging 12.8 points, 8.6 rebounds and 1.1 blocks over just 25.3 minutes per game.

Porzingis did get 31 minutes in Tuesday's historic performance, marking his second-highest total through 12 appearances this season.

Cleveland Cavaliers forward LeBron James achieved yet another milestone during Tuesday's 104-99 loss to the Detroit Pistons, passing Hall of Famer Jerry West (25,192 career points) for sole possession of 19th place on the NBA's all-time scoring list, per Sportsnet Stats.

Despite making 11 of his 21 field-goal attempts in a 30-point performance, James was unable to lead his team to victory, as Detroit Pistons center Andre Drummond (25 points, 18 rebounds) and point guard Reggie Jackson (23 points, 12 assists) both turned in huge performances.

The 8-3 Cavaliers have now lost their last two games by a combined eight points, after winning each of the previous eight contests.

Even with star point guard Kyrie Irving still sidelined, the James-led Cavs have proven to be one of the toughest teams in the Eastern Conference, sporting the best record and second-best point differential (+6.1 per game).

Golden State Warriors point guard Stephen Curry has poured in 404 points so far this season, tying Michael Jordan for the second-most points scored through the first 12 games of a campaign since 1992-93, per Sportsnet Stats.

The 27-year-old superstar has at least 22 points in every contest this season, most recently scoring 37 in Tuesday's 115-100 win over the Toronto Raptors.

His Warriors are off to a sterling 12-0 start, with Curry's averages of 33.7 points, 5.9 assists, 4.8 rebounds and 2.4 steals playing a huge role in the early-season dominance.

Even more impressive, he has made 52.1 percent of his shots from the floor and 45.6 percent of his three-pointers, despite leading the league in both field-goal attempts (21.6) and three-point attempts (11.3) per game.
