Dez Bryant tweaked his knee during the first series of Sunday night's game against the Bears. The Cowboys' wideout returned after missing a few plays and ended the evening with three receptions for 40 yards and a touchdown.

After the game, owner and general manager Jerry Jones suggested that Bryant would have an MRI on Monday. On Tuesday, during an interview with CBS Radio's 105.3, Jones said the MRI never happened -- though it could still take place -- and added, "I'm assuming he's a go" for Sunday's matchup against the 49ers.

The Cowboys have other injury concerns too, and Jones addressed some of those. Second-year left guard La'el Collins is out 6-10 weeks with a torn ligament in his foot.

"Right now, he's less likely to have surgery, it's a pain thing ... we'll see how he tolerates it," Jones said of Collins' prognosis. "He has a high tolerance for pain. He'll probably not have surgery and see if he can work through this."

Then there's Collins' line mate, left tackle Tyron Smith, who missed the Bears game with a back issue.

"I hope Tyron is ready to go, we'll just have to see, we thought he would play Sunday and that was a little surprise for us," said Jones. "It was more back spasm than structure," adding, "I'm going on the basis he'll play."

Defensive back Orlando Scandrick, who also missed the Bears game with a hamstring injury, appears less likely to face the 49ers. "We'll have to be real careful, you've gotta' nurse those along," Jones explained.
