Oklahoma football notebook: Why Texas didn't kick the final extra point against OU

The referee announced the game had ended after the touchdown and no PAT would be attempted.

According to the NCAA's rules, if a touchdown is scored as time expires, the period can be extended for a PAT attempt, unless it happens in the fourth quarter and the extra points would not affect the game's outcome.

A similar situation occurred during Week 3 of the NFL season, but with different results. Seattle quarterback Russell Wilson lofted a pass into the end zone as the final seconds expired in the Seahawks' game against the Green Bay Packers.

In Seattle, the field was flooded with players, media and absolute confusion. The Packers ran to their locker room before the final PAT was attempted, but eventually came back out for the attempt because NFL rules require it; point differential is a playoff tiebreaker.

JEFFERSON EARNS WEEKLY THORPE HONOR

Oklahoma City's weekly college football award is finally staying in-state.

OU safety Tony Jefferson was named the Jim Thorpe Defensive Back of the Week on Wednesday afternoon, making him the second Big 12 player (but first in the state) to win the weekly award this season.

Jefferson played a starring role in the Sooners' 63-21 domination of Texas in Dallas on Saturday, recording a team-high seven tackles (including two for a loss) and one interception.

Jefferson, an immediate star at Oklahoma, has been a key cog in the Sooners' defensive resurgence under new (and old) coordinator Mike Stoops this year.

He leads OU with 37 tackles, including a career-high 14 in the loss to Kansas State, often looking like the best player on the field and a guy who could soon be doing this for a living on Sundays.

Before the season, Jefferson was placed on the Jim Thorpe preseason Watch List. And, given the way he's played, there's a decent chance he'll be named a finalist for the Thorpe Award later this season, given out annually at the Jim Thorpe Museum in Oklahoma City to the nation's best defensive back.
