The 49ers suffered a major blow during OTAs, as wide receiver Michael Crabtree suffered what could be a season-ending injury.
According to Mike Garafolo of USA Today, Crabtree tore his Achilles during a workout Tuesday, and will need surgery to repair the injury.
While players such as Terrell Suggs and Da’Quan Bowers have come back in the same season from such injuries, those cases are rare.
The 25-year-old Crabtree emerged as a threat last year, with 85 catches for 1,105 yards and nine touchdowns, and an impressive postseason.
Without him, the 49ers offense doesn’t look nearly as potent.
They haven’t shown any interest in bringing back Randy Moss, and though they acquired Anquan Boldin in a trade with the Ravens, they now lack a proven downfield threat.
