SAN ANTONIO ? Mike Allen kicked a 37-yard field goal in overtime, sending Wisconsin to a 31-28 win over No. 14 Colorado in the Alamo Bowl on Saturday night.

Wisconsin’s Brooks Bollinger threw two touchdown passes and ran for the tying score with 51 seconds left in regulation. The Badgers (8-6) improved to 7-1 in bowl games under coach Barry Alvarez.

Allen, a walk-on, had to shake some jitters before his winning kick.

“I haven’t been automatic from 37,” said Allen, who was 11-of-18 this season with a long of 48 yards. “Luckily, today I was.”

Colorado (9-5) got the ball first in overtime but lost 2 yards on three plays before Patrick Brougham missed a 45-yard field goal attempt.

Wisconsin then gained 5 yards on three straight runs to set up the winning kick by Allen, who was mobbed by his teammates on the field.

“How ’bout them Badgers!” Alvarez yelled to the Wisconsin fans as the Badgers celebrated the win amid hundreds of multicolored balloons and confetti dropped from the Alamodome ceiling.

Bollinger passed for 163 yards and ran for 82 more in the senior’s eighth career fourth-quarter comeback.

“No question about it, this program needed this so bad,” Bollinger said. “Especially for the young kids, to point this program in the right direction.”

Chris Brown rushed for 97 yards and a touchdown on an Alamo Bowl-record 28 carries for Colorado.

Brown, who rushed for 1,744 yards during the season but missed the last two games because of a bruised sternum, also missed most of the fourth quarter because of a concussion.
