Philadelphia Eagles right tackle Lane Johnson announced Friday that his season is over as he awaits ankle surgery.

"It's like the inside of my ankle is collapsed," Johnson said, "so a lot of my power and my push-off that I normally have isn't there."

Johnson said a stress fracture was forming from the tightrope surgery he had to repair a lingering high ankle sprain a couple of weeks before the start of the season. He felt he was making progress physically, but the leg was rolled up on a few times in the ensuing weeks, setting him back.

The surgery is a repair of the deltoid ligament, Johnson said, damaged from "all of the high ankle sprains and damage I had done to my ankle." He expects a recovery period of four to five months.

Johnson indicated Matt Pryor will take over at right tackle and veteran Jason Peters will move to right guard. Jordan Mailata would then get the nod at left tackle.

Johnson, 30, has already missed three games this season to injury, and he was sidelined for four games in 2019.
