Poteet (triceps) will begin a rehab assignment with Double-A Somerset on Tuesday, Gary Phillips of the New York Daily News reports.
Poteet has been shelved since mid-June with a right triceps strain and is finally ready to test things out in a game setting. The right-hander figures to require a handful of rehab appearances and it's not clear whether the plan is to stretch him back out to start or prepare him for a bullpen role.
