Here is the latest Big 12 Conference sports news from The Associated Press

AUSTIN, Texas (AP) — Once upon a time, Jerrod Heard had "the juice." He was the quarterback of the future for the Texas Longhorns and he'd just smashed Vince Young's single-game school for total offense. He could throw. He could run. He could do just about everything. Then all that juice dried up with a whole lot of losing. A fifth-year senior, Heard heads into his final home game this week as a fifth-option wide receiver and special teams guy. But he's still got the record a whole lot of respect from his teammates.

NORMAN, Okla. (AP) — Oklahoma offensive lineman Tramonda Moore has been dismissed for violating team rules. The school made the announcement in a news release Tuesday. The 6-foot-4, 322-pound Moore never played for the No. 6 Sooners.

LUBBOCK, Texas (AP) — Jarrett Culver scored 21 points, Norense Odiase grabbed a career-best 13 rebounds and Texas Tech shrugged off Southeastern Louisiana for a 59-40 victory. Culver scored six points in the final 1:58 before halftime to give the Red Raiders a 32-19 lead. Texas Tech is 3-0 and hasn't trailed this season.

FORT WORTH, Texas (AP) — TCU starting senior defensive tackle Joseph Broadnax isn't expected to play again because of an undisclosed medical condition initially discovered during a preseason screening. Coach Gary Patterson says he can't elaborate but that an MRI during the summer found something in the early stages that was OK then. Broadnax didn't play Saturday at West Virginia after showing signs related to the condition, including weakness in his arm.

UNDATED (AP) — The College Football Playoff rankings held steady at the top, with Alabama, Clemson, Notre Dame and Michigan an unchanged first four from last week. The third rankings of the season were drama-free after every top-10 team won last weekend.

AMES, Iowa (AP) — No. 18 Iowa State will be without junior David Montgomery, one of its best players, for the first half of one of the bigger games in recent school history. How the Cyclones fare for 30 minutes without their star running back could decide whether they can stay alive for a spot in the Big 12 title game. Montgomery will miss the first two quarters of a showdown at No. 13 Texas on Saturday after being ejected for throwing a punch during last week's win over Baylor.
