Cards being cautious with Wells

Coach Ken Whisenhunt said RB Beanie Wells will continue to work on the side and avoid team drills as he rehabs from offseason knee surgery. "We're expecting to have both of these guys ready to go by training camp," Whisenhunt said of Wells and RB Ryan Williams, who is rehabbing following surgery for a torn patellar tendon. "Whatever we can get from them in the next two weeks would be a bonus."
