AUSTIN, Texas — Colt McCoy set an NCAA record with his 43rd career victory as a starter, passing for 396 yards as No. 3 Texas wrapped up the Big 12 South title with a 51-20 victory Saturday night over a Kansas and embattled coach Mark Mangino.

McCoy is 43-7 in his career, breaking the wins record he shared with former Georgia quarterback David Greene (2001-2004).

Texas (11-0, 7-0) secured its first division title since 2005, with a Thanksgiving game at rival Texas A&M left to play before the Big 12 championship on Dec. 5.

McCoy threw four touchdown passes, two to James Kirkendoll.

McCoy’s big night and two more games to shine on national television could give his Heisman Trophy hopes a big late-season boost. He has 23 touchdown passes this season with 2,996 yards.

Unlike other games when Texas was winning big and McCoy watched the fourth quarter from the sideline, he stayed in against Kansas until late to say a final goodbye to the home fans.

Kansas (5-6, 1-6) dropped its sixth straight, compounding a miserable week and season for Mangino. University officials have confirmed they are investigating Mangino over allegations of emotional and verbal abuse of players, fueling speculation he may be fired.

Kansas put up some of the best numbers of the season against the nation’s top-rated defense. Jayhawks quarterback Todd Reesing passed for 256 yards. Dezmon Briscoe had a 98-yard kickoff return for a touchdown.
