The Mets don't expect to get outfielder Jason Bay back this season.
Bay suffered a concussion at Dodger Stadium four weeks ago while crashing into the left-field wall.
"That's the way I see it," manager Jerry Manuel said. "I could be way out of line, or way out of bounds. But that's the way I see it."
A team official said Bay cannot go 48 hours without a recurrence of concussion-related symptoms.
