Kentucky senior running back Derrick Locke suffered a slight crack in the ulna bone in his left forearm during a moped accident this week, UK officials said Friday.
Locke lost control of the moped and suffered the injury trying to regain his balance. He will be in a splint for four weeks and will then be re-evaluated. The injury does not require surgery.
UK opens fall practice in early August. Kentucky's season opener is Sept. 4 at Louisville.
Locke, who ranks 10th on UK's all-time rushing list, is expected to be the Wildcats' starting tailback this season.

He was honored after the 2009 season as an All-Southeastern Conference second-team performer as an all-purpose player.
