SAN DIEGO -- A familiar face at Chargers Park, inside linebacker Donald Butler wore the same No. 56, but he's in a differently colored jersey during joint practices between the San Diego Chargers and the Arizona Cardinals this week.
The University of Washington product signed a non-guaranteed one-year, $800,000 deal just before training camp opened at the end of July with the Cardinals.
Butler is currently No. 3 on the depth chart for Arizona at inside linebacker and fighting for a spot on the back end of the roster for one of the NFL's best teams.
