The Philadelphia Eagles were hit with another injury to the offense on Sunday night.

Three plays into their game in San Francisco, offensive lineman Lane Johnson went down with an injury.

Johnson was seen walking to back to the Eagles training room to get looked at for an injury to his ankle.

He missed the Eagles Week 1 game in Washington after having ankle surgery.  Rookie Jack Driscoll, who stared in Week 1 replaced him at right tackle.

So the Eagles current tackles are Jordan Mailata and Driscol with Nate Herbig and Matt Pryor at guard and Jason Kelce at center.

Update: Johnson returned to the field after missing just one series, and then left again and is listed as questionable to return.
