Colin Kaepernick Video: Watch 49ers QB's Record-Breaking TD Run

Mike Hoag@MikeHoagJrCorrespondent IIJanuary 12, 2013

Colin Kaepernick set the NFL postseason single-game rushing record by a QB with his 56-yard touchdown sprint, according to to Will Brinson of CBS Sports.

Kaepernick faked the handoff to running back LaMichael James on a designed read-option play and then took it untouched 56 yards for the go-ahead touchdown.

It was the type of play that makes you shake your head in amazement and applaud.

The Packers' defense wasn’t even close after Kaepernick broke it to the second level. Their D has been beaten by the run this season, but it hasn’t been this bad.

San Francisco‘s success running the football is thanks to the poor run defense of the Packers, but also a credit to its offensive line’s success up front.

The Niners dominated at the line of scrimmage and that forced the Pack to close down on the running backs, freeing up Kaepernick to make plays.

And make plays he did.

After the big run, the sophomore QB's rushing total had reached 163 yards with two touchdowns. That was with 7:07 remaining in the third quarter.

Not only did he break the record, but he set himself up with the potential to shatter it in the remainder of the game.

He finished the game with a remarkable 181 yards rushing, the most by any QB, in ANY NFL game, according to Vic Tafur of the San Francisco Chronicle (via Twitter):

That 16-yard run gives Kaepernick the NFL record for rushing yards by a QB (in any game), with 179 yards. #49ers

He didn't just run the ball, either. His two rushing touchdowns were solidified with two more through the air and 444 yards of total offense.

Alex Smith guided the 49ers to a pace-setting Week 1 victory over the Packers at Lambeau Field. He was an efficient 20-of-26 passing for 211 yards and two touchdowns.

There was certainly nothing wrong with Smith's performance.

Quarterback change aside, the result is not much different for the 49ers four months later. They are still up on the Packers, but have taken quite a different path to get there.

Kaepernick has added a whole new element to the team’s offense and exploded here on the huge stage of the NFL playoffs.
