CHARLOTTE, N.C. -- The Carolina Panthers shored up their banged-up secondary by signing safety Gerald Alexander on Tuesday and added yet another quarterback to their practice squad.
The Panthers waived wide receiver Devin Thomas to make room for Alexander, a Boise State product who was the Detroit Lions' second-round draft pick in 2007 and played for the Jacksonville Jaguars this season. Carolina reserve safeties Jordan Pugh and Marcus Hudson are injured.
Keith Null becomes the latest Panthers quarterback, and linebacker Sean Ware was placed on practice-squad injured reserve to make room. Null started four games last season as a rookie with the St. Louis Rams and threw three touchdowns and nine interceptions.
The Panthers hope rookie Jimmy Clausen will be cleared this week following a concussion. Last week's starting quarterback, Brian St. Pierre, complained of a sore shoulder Monday.
