The Chargers officially have announced the arrival of 21 undrafted free agents. They’ve also signed one veteran: offensive lineman Rex Hadnot.
Hadnot, an eight-year veteran, started 16 games for the Cardinals in 2011. He previously played for the Browns and Dolphins.
In San Diego, Hadnot will join a group of guards that includes Louis Vasquez, Tyronne Green, Brandyn Dombrowski, and rookie fifth-rounder Johnnie Troutman. The Chargers lost Kris Dielman to retirement, who had a seizure after suffering a concussion against the Jets.
