Oklahoma coach Bob Stoopssounded like a believer Tuesday.
"I'm pretty convinced of that," Stoops said. "Things may change, but at this point it hasn't for him."
Peterson was hopeful to return from a broken collarbone in time to play in Saturday's Bedlam game. That possibility was ruled out after a bone scan done Monday.
Stoops said he was uncertain whether Peterson might make it back should the Sooners make the Big 12 title game Dec. 2. Peterson's father, Nelson Peterson, said Monday that his son still wanted to play for OU in a bowl game.
As for the long layoff — the injury occurred Oct. 14 and a late-December or early January bowl is expected for the Sooners — Stoops said it's no concern.
"He's out there running and doing things, training," Stoops said. "He's in shape.
"All right, so he's 80 percent, instead of 100. Still pretty good."
• Eyes on Texas: OU players and coaches are dismissing thoughts of a possible letdown related to Friday's Texas-Texas A&M game.
An A&M win would set up the Sooners with a shot at the Big 12 championship game, provided they beat OSU. A Texas win seals a Longhorn clash with Nebraska in Kansas City.
"There is some big implications on that game," said Sooners quarterback Paul Thompson. "Either way, if we don't take care of Oklahoma State, it doesn't matter.
"It's a tough situation, because it is an important game, as far as where we want to go. But at the same time, playing Oklahoma State is just as important."
Thompson pointed out that this team has been able to stay focused through much adversity this season.
"This team has proved that we can block out a lot of things and stay focused on what we need to do," Thompson said. "This is just another thing we have to block out."
