TEMPE, Ariz. � Wide receiver Anquan Boldin and defensive tackle Darnell Dockett showed up for the Arizona Cardinals minicamp but begged off of workouts because of "injuries."

Both players are upset with their contract status and coach Ken Whisenhunt told reporters that everyone knows what is really going on with their absence. He declined to elaborate. Whisenhunt said both were sent for MRIs after reporting injuries of which the team had been unaware.

Two other players with unsettled contract issues � linebacker Karlos Dansby and safety Adrian Wilson � participated in Friday's first workout, although Dansby was late because of what he said was a mixup over what time the practice started.
