Troy Aikman, who has missed two games after his ninth concussion, will be back in the starting lineup for Dallas against San Francisco.
Cowboys owner Jerry Jones said Wednesday night that, based on a post-practice evaluation of Aikman, the quarterback would indeed start Sunday's game.
"There is no reason at this time to delay him from competing," Jones said. "Our plans had been all along this week to evaluate Troy when he came into to start this week. He is ready to go."
Before practice, Aikman said he had met with team doctors, who told him he was clear to play.
"They say it's a decision I can make. I'm feeling good," Aikman said. "The idea is that I will be playing this week. I feel like I'm capable of doing that, and am looking forward to it."
Randall Cunningham started at Arizona and Washington. Aikman practiced throughout last week but was held out again against the Redskins. The Cowboys won, 27-21, with Cunningham throwing for 185 yards and two touchdowns.
