Chargers head coach Brandon Staley said Tuesday that Hopkins (hamstring) will be out 2-to-4 weeks, Lindsey Thiry of ESPN.com reports.
Hopkins remained in Monday's game after initially suffering a hamstring injury on his first kick of the contest and ended up connecting on four field goals, including a game-winning 39-yarder in overtime. It's unclear if staying in the game made the hamstring issue worse, but the Chargers may not have come away with a victory without Hopkins' persevering performance. In Hopkins' absence, Los Angeles is expected to promote Taylor Bertolet from its practice squad to serve as the primary kicker against Seattle.
