Arizona Cardinals defensive lineman Dan Williams suffered injuries to his knee and ankle during practice Thursday.
Williams sprained his medial collateral ligament and his ankle during the first live tackling session of Cardinals training camp. He underwent an MRI, which revealed no major structural damage, said Cardinals head coach Bruce Arians.
Neither injury will require surgery. His ankle injury is considered more serious than that to his knee.
"It was scary just being rolled up on. And I'm thinking it's a torn something," Williams said Friday. "I'm just happy that the MRI came clean, and I'm glad I won't miss that much time."
He said he wants to play in the first preseason game against Green Bay next week, but he's going to listen to the team's trainers and see how rehabilitation goes before deciding to play or not. The knee injury alone normally would keep a player out three to four days, but the additional injury means he may need more time before hitting the field again.
Williams is entering his fourth NFL season. The 6-foot-3 nose tackle recorded a career-best 44 combined tackles in 2012, playing in 15 games for the Cardinals.
