ICON Sport has been forced to indefinitely postpone their December 15 “Fearless” event after Robbie Lawler suffered a bicep injury that forced him to withdraw from his main event bout against Kala Kolohe Hose.

Lawler is both the EliteXC Middleweight Champion and the ICON Middleweight Champion. He claimed the ICON Sport middleweight title in March with a win over Frank Trigg then won EliteXC’s belt in September by defeating Murilo Rua.

Lawler, who co-owns a gym with former-UFC Champion Matt Hughes, is not expected to need surgery.
