Cincinnati Bengals left tackle Jonah Williams sustained a dislocated left kneecap during a playoff victory over the Baltimore Ravens on Sunday.

Williams did the damage in the second quarter of a 24-17 Wild-Card round win and was replaced by Jackson Carman.

The 25-year-old was on Monday listed as week-to-week by the Bengals, who battle the Buffalo Bills in the Divisional round at Highmark Stadium on Sunday.

Bengals head coach Zac Taylor said it was "hard to tell" if Williams will recover in time to take on the Bills but was impressed with the way Carman stepped in.

"I thought he did a nice job, especially being thrust in there," Taylor said. "He's gotta practice both sides during the week.

"He's practised a lot of guard this year as well. I thought given the opportunity that he had, against a tough defensive line, I thought he handled it really well."

Alex Cappa missed the game against the Ravens due to an ankle injury, but Taylor was encouraged to see him in attendance wearing a protective boot.

"I saw him curling a towel in there with his toes and he looked good," Taylor said. "It seemed like that was progress when I walked in. That was exciting for the room."
