Philadelphia Eagles right tackle Lane Johnson suffered a possible concussion in the first half of his team’s Week 5 win over the Arizona Cardinals on Sunday.

Eagles head coach Doug Pederson would not confirm the injury after the game.

"I can't confirm at this time until we get more information with him," Pederson said.

Philadelphia replaced Johnson on Sunday with Halapoulivaati Vaitai and its possible that Vaitai will get the start on on Thursday night in Carolina against the Panthers. Johnson will have to pass the leagues concussion protocol, which is unlikely to happen on a short week.

"We didn’t miss a beat," Pederson said. "Big V stepped up and it seemed like he did a great job. We’ll go back and watch tape. We know Lane’s a heck of a football player. Hopefully he can recover and be ready to go. We’ll see what happens, but at the same time, Big V’s had tons of valuable experience and reps last year and he got a ton better, so we feel solid if Lane’s not ready to go. We know Big V will be ready.”

The Eagles were 2-8 without Johnson at left tackle last season, 5-1 with him in the lineup.
