Anquan Boldin was present for the Cardinals' first mandatory off-season event on Friday, according to the Arizona Republic.
Darnell Dockett and Karlos Dansby were reportedly a part of the workouts, as well.
Boldin was rumored to be upset with his current contract situation because fellow receiver Larry Fitzgerald is getting paid a significant amount more for his services.
