Erik Bedard may not make his season debut for the Mariners until late June.
Seattle manager Don Wakamatsu on Thursday described a plan that suggests he won't be ready for roughly a month.
The Mariners had hoped that he'd pitch in a week or so, but he had a setback last week when he felt discomfort while throwing 30 pitches in a simulated game.
