Tom Zbikowski is hanging up his boxing gloves so he can "transition back to football." The Ravens safety has pulled out of his June 4 fight against Mike Howell at the Staples Center so he can join his teammates for informal workouts during the lockout. "It was time to start the transition back to football," Zbikowski told the Los Angeles Times in a text message. "My teammates are starting to organize some workouts, so it's just time to head back (to Baltimore). Wish I had more time to do both." Zbikowski was 3-0 in his return to the boxing ring during the NFL's work stoppage.
