SANTA CLARA — The San Francisco 49ers suddenly have a huge void in their receiving corps as they chase another Super Bowl berth: Michael Crabtree is sidelined after surgery on his right Achilles tendon.
San Francisco's leading wide receiver underwent surgery Wednesday, though the team is optimistic he will return at some point in 2013. Crabtree was operated on at Stanford by Dr. Tim McAdams one day after suffering the injury during 7-on-7 drills in an organized team activity.
"Michael Crabtree underwent surgery to repair his Achilles tendon that he tore yesterday," coach Jim Harbaugh said. "Surgery was successful and we do not anticipate it will be season-ending for Michael. It was completely torn, and completely repaired."
Harbaugh would not speculate when Crabtree might return to play.
The 25-year-old Crabtree, the team's 10th overall pick in the 2009 draft out of Texas Tech, had career highs last season with 85 receptions for 1,105 yards and nine touchdowns for the NFC champion Niners, who lost 34-31 to the Baltimore Ravens in the Super Bowl.
