One of the deepest receiving corps in the SEC has taken a hit.

Arkansas senior London Crawford broke his collarbone in the season-opening win over Missouri State and will miss the next four to six weeks. Crawford, who had two catches for 44 yards in the opener, underwent surgery Monday morning. He started in 11 games last season for the Hogs.

Thirteen different players caught passes for Arkansas in Saturday's game.
