Eagles starting right tackle Lane Johnson had to be carted off the field to get his troublesome ankle looked at on Sunday in Pittsburgh.

On Monday, Eagles head coach Doug Pederson did not give an update on the injury, but did divulge that Johnson was seeking a second opinion on the injury.

"Medically we're waiting on a second opinion, so there's some reports still coming in on Lane, so I don't have any update yet with him," Pederson explained.

Remember Johnson missed the Eagles Week 1 game in Washington after ankle surgery for a clean out. He also had to leave last week's game in San Francisco with the same injury.

With Johnson potentially out, the Eagles would be down four of their projected starters, Andre Dillard, Isaac Seumalo, Brandon Brooks and Johnson. Rookie Jack Driscoll will likely play at right tackle if Johnson is to miss any time, which from the sound of it, is likely.

Pederson also said that cornerback Darius Slay was in the concussion protocol.

"Obviously, Darius Slay is in the concussion protocol right now. So obviously can't comment any further on that."
