Chargers place OL Trey Pipkins III on IR, sign QB DJ Uiagalelei to active roster

Pipkins, who was ruled out for Week 3 with a knee injury, will miss at least the next four games.

With Kayode Awosika (fibula) also ruled out, Trevor Penning will start at left guard.

In a corresponding move, the team signed quarterback DJ Uiagalelei to the active roster. In addition, the Chargers elevated tight end Patrick Herbert and outside linebacker Caleb Murphy from the practice squad for Sunday's game.
