Lubbock, Texas ? Coach Mike Leach wasn’t happy about Texas Tech’s six turnovers Saturday night — all by B.J. Symons — but he was satisfied with the outcome.

Symons threw five interceptions, had a season-low one touchdown pass and failed to throw for at least 400 yards for the first time in eight games, but Tech still managed to come back and beat Colorado, 26-21.

“B.J. was a little out of sync,” Leach said. “He had to fight all day, and it’s a credit to the rest of the team that he came out on top.”

Symons was 30-of-51 for 399 yards and tied a school record for interceptions. He became the 22nd quarterback in NCAA Division I-A history to throw for 4,000 yards and the second in Big 12 Conference history after former teammate Kliff Kingsbury.

Leach never lost his cool with Symons.

“He never really got angry,” Symons said. “He has told me to continue to go through my reads and to continue to play.”

Tech (6-3, 3-2 Big 12) went ahead for good midway through the third quarter when Symons threw a 13-yard touchdown pass to Wes Welker — who also set the NCAA Division One record with his eighth career punt return for a touchdown.

Welker, who had 211 all-purpose yards, gave Tech a spark late in the first half when he returned a punt 58 yards for a TD to cut Colorado’s lead to 14-9.

“We had a wall return set up down the left sideline, and basically we had some good blocks,” Welker said. “The record means a lot. It’s an NCAA record. I’ll see how long I get to hold onto it. I want to enjoy it while I can.”

Welker had been tied at seven with Nebraska’s Johnny Rodgers, Kansas State’s David Allen and Jack Mitchell of Oklahoma. OU’s Antonio Perkins also has seven.
