GLENDALE, Arizona -

The Arizona Cardinals concluded their first day of training camp with a flurry of personnel moves.
    
The team announced that rookie wide receiver Ryan Swope was retiring because of concussion issues. The Cardinals placed the former Texas A&M star on the reserve/retired list, meaning he would be Arizona's property if he returned to the sport. Swope, drafted by Arizona in the sixth round, set school records for receptions and yards receiving for the Aggies but was plagued by concussion issues and had a serious setback in the early summer.
    
The team added two experienced players, agreeing to a one-year deal with offensive tackle Eric Winston and on a two-year contract with outside linebacker John Abraham. The Cardinals also released outside linebacker O'Brien Schofield, a former starter, and signed linebacker Kenny Rowe.
    
Winston, a starter in all six of his NFL seasons, signed a one-year deal after failing to find a better offer. He says he knows he has to compete but expects to win the right tackle job. Abraham is a 14-year NFL veteran and the league's active leader with 122.
