Howard has been recovering from an Achilles injury which he had surgery on to repair in October 2011. After seemingly being ahead of schedule, Howard had a setback when he developed an infection around the site of the surgery. He needed another procedure to deal with the infection.
Howard is still rehabbing in Florida and doing baseball activities. However, the team is being cautious because they don't want to risk an injury to another part of his body due to muscle atrophy in his calf.
When asked to comment about Howard's return, Phillies general manager Ruben Amaro Jr. said he was uncertain whether or not Howard could return in June, or even by the All-Star break on July 8.
