American Honda has announced that Ben Townley's return to AMA competition has been delayed due to rehabilitation complications.

After winning the 2007 East Lites Supercross title, then battling Pro Circuit Kawasaki team-mate Ryan Villopoto tooth and nail for the Motocross Lites Championship, the New Zealander made the switch to Honda, but was sidelined for much of the 2008 season.

"Ben has been training on his CRF450R for about a month and continues to have difficulty with his shoulder," explained team manager Erik Kehoe. "He is working with Red Bull's elite athlete training staff and will be meeting with several shoulder specialists to identify the cause of the problem and choose the best course of action to expedite his recovery. Our goal is to make sure he is 100 percent before he returns to racing."

It may be several weeks before Townley can establish a course of action for treatment.
