English day-to-dayOklahoma coach Bob Stoops said Sunday that defensive end Auston English will be monitored daily to see if he can play in the Big 12 Championship game against Missouri at 7 p.m. Saturday. Stoops also confirmed that running back DeMarco Murray will not play again this season. The freshman will undergo surgery to repair his dislocated kneecap later this week. English broke a non-weight-bearing bone in his right ankle Nov. 3 against Texas A&M and had a pin inserted to stabilize the hairline fracture. Sooner coaches were pleased with the performance of redshirt freshman defensive end Jeremy Beal, who started in place of English on Saturday against Oklahoma State. Beal delivered the hit of the game when he knocked the helmet off OSU quarterback Zac Robinson's head. "I didn't know I had knocked it off until I saw it on the ground,” Beal said. "I said ‘Where'd that come from?' It felt pretty good to knock his helmet off.” •Going against No. 1: Though The Associated Press Top 25 poll carries less weight than it once did, it is still one of the most highly regarded ranking systems in college football. And in the poll released on Sunday, Missouri claimed the top spot heading into Saturday's meeting with Oklahoma in the Big 12 Championship game in San Antonio. That could be a bad sign for the Sooners, who are 6-12-2 all-time when facing the AP No. 1 team. OU's last meeting with an AP No. 1 was the 55-19 loss to USC in the 2005 Orange Bowl. OU's last victory over an AP No. 1 was the 31-14 win over Nebraska in Norman on Oct. 28, 2000.
