The fantasy football regular season is winding down. For some leagues, this week marks the start of the playoffs. For others, this is the final week of the regular season.
Either way, fantasy owners could be looking to give their team a final boost to push it to more success and potentially a league championship. It's never too late in the season to keep an eye on the waiver wire and add depth just in case of injuries or find a better player for a weak spot in your lineup.

Week 13 Waiver-Wire Targets and Projections
Tennessee Titans WR A.J. Brown
Brown has had boom-or-bust potential all season, and the rookie first-round receiver has a high ceiling as he showed this past Sunday. For the first time since Week 1, Brown reached the 100-yard mark as he had four receptions for 135 yards and a touchdown in the win over the Jaguars.
Over Tennessee's previous six games, Brown had only one touchdown. His only other two scores of the season had come in Week 4 at Atlanta.
But the Titans offense has been moving the ball more efficiently with Ryan Tannehill at quarterback, which gives Brown more fantasy potential. This week, Tennessee plays Indianapolis, which is a middle-of-the-pack team in pass defense, and it has won four of its last five games entering this big AFC South clash.
If you need a fill-in at receiver or in the flex spot, take the chance on Brown having another solid game this week and again getting into the end zone on a big play.
Buffalo Bills WR Cole Beasley
Although the Cowboys have a top-10 passing defense, Beasley will have some extra motivation for the Bills' Thanksgiving Day game in Dallas. He played for the Cowboys from 2012-18, and this will be his first time playing against his former team.
The 30-year-old will also be close to home, as he went to nearby Little Elm High School before spending his college career at Southern Methodist University.
Those factors make Beasley an intriguing fantasy option this week, especially considering his consistent production this season. He's had a touchdown in four of Buffalo's last six games, including its win versus Denver on Sunday when he had six receptions for 76 yards.
The slot receiver is going to be a big part of the Bills offense against the Cowboys, and count on him to break off a big play or two against some of his former teammates.
Seattle Seahawks RB Rashaad Penny
There's been fantasy potential for Penny this season, but he's been blocked by Chris Carson in the Seahawks backfield. But Penny finally got some opportunities Sunday against the Eagles, and he capitalized on them by rushing for 129 yards and a touchdown on 14 carries.
Prior to that, Penny had only 167 rushing yards and a touchdown through Seattle's first 10 games. But he's now proved that he should get more touches moving forward.
The Seahawks have a tough matchup this week against the Vikings, who rank sixth in the NFL in run defense (94.2 yards allowed per game). However, if Carson gets stopped early, that brings a greater possibility of Penny getting involved in Seattle's offense again.
For fantasy owners who are heading to their league's playoffs, Penny has even more potential to make an impact as he has some favorable matchups against the Panthers and Cardinals in Weeks 15 and 16.
