CLEVELAND (WJW) – Cleveland Browns linebacker Anthony Walker Jr. will have season-ending surgery for the injury he suffered in Thursday night’s win over Pittsburgh, according to reports.

ESPN’s Adam Schefter reported Friday that an MRI showed Walker tore his quad tendon. It’s estimated to take 5 to 7 months to recover from the injury.

It happened during a controversial non-call.

Steelers Chukwuma Okorafor jumped on Walker when he was face down on the field. Okorafor was not penalized for the hit.

Walker is in his second season with the Browns and a team captain.

“It’s a huge loss with Anthony Walker if this is a longer-term thing,” Brown coach Kevin Stefanski said before the MRI. “We know what he brings to the football side of things, but he’s a captain and he’s a leader, so we got our fingers crossed and definitely hoping for the best for No. 5.”

Walker had 6 tackles before his injury Thursday.

The Cleveland Browns did not confirm the extent of the injury but did say late Friday that Walker had been placed on injured reserve.
