The Arizona Cardinals have placed starting right tackle Jonah Williams on injured reserve after he sustained a knee injury during their season-opening loss to the Buffalo Bills.

Head coach Jonathan Gannon shared the news on Wednesday but refrained from giving a specific timeline on Williams’ return, saying, “I’m not going to speculate.” With his placement on IR, Williams will miss a minimum of four games.

Veteran tackle Kelvin Beachum is expected to step in, having taken over for Williams immediately following the injury.

“Whoever steps in, we feel confident in their ability,” Gannon said. “Beachum brings a lot of experience, so there’s a comfort level with him, but we trust that anyone who plays will be ready to get the job done.”

The 6-foot-5, 312-pound Williams joined the Cardinals this offseason on a two-year, $30 million deal after spending four seasons with the Cincinnati Bengals. A former Alabama standout, he was selected 11th overall in the 2019 NFL Draft.
