SAN DIEGO -- The San Diego Chargers made a couple moves to add depth to an ailing offensive line on Tuesday.
After releasing tight end Kyle Miller and placing guard Johnnie Troutman on the season-ending injured reserve earlier in the day, the Chargers filled those two roster spots by signing center J.D. Walton and promoting undrafted rookie Tyreek Burwell from the practice squad to the active roster.
Walton missed the entire 2013 season and almost all of 2012 due to ankle injuries while with the Denver Broncos. A third-round selection by the Broncos in the 2010 NFL draft, Walton played for Chargers head coach Mike McCoy while he served as offensive coordinator for the Broncos. Walton will wear No. 66.
The Chargers filled Burwell's spot on the practice squad by bringing back guard Michael Huey.
