The Los Angeles Chargers placed starting center Mike Pouncey on injured reserve with a neck injury on Wednesday.
In a corresponding move, the Chargers signed guard/center Ryan Groy to the vacant roster spot.
Pouncey is eligible to return to the active roster but will have to miss eight weeks. He suffered the injury in the Chargers’ loss to the Denver Broncos on Sunday.
Los Angeles (2-3) will likely move Dan Feeney from left guard to center in place of Pouncey, and move third-year lineman Forrest Lamp into the starting rotation at left guard in place of Feeney.
The Chargers began the season without starting left tackle Russell Okung, who was placed on the non-football illness list in August due to a pulmonary embolism caused by blood clots he suffered during a workout in June.
