"He has gotten better," Stoops said. "We're expecting him to play and practice more tomorrow."
Both came up big, and Stoops said there is still a chance for defensive tackle Quincy Russell to make an impact. After playing initially, Russell has not seen the field.
"He's coming along," Stoops said. "He's just catching up, refining his technique."
The other question heading into the Red River Rivalry revolves around the linebacker spot. Senior captain Corey Nelson suffered a partially torn pectoral muscle in the third quarter.
"Really good," said Stoops about Alexander this week. "He and Aaron Franklin have done a really good job. We like what they're doing."
Stoops said they will name a starter eventually but didn't confirm it was Alexander on Wednesday night.
Nelson has delayed his surgery at this point so he can be on the sidelines Saturday and help the linebackers out. He will not be suited up.
