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.
