Muller's Ulster return ahead of schedule
Ulster captain Johann Muller is expected to be back in action ahead of schedule to give his side a boost before a testing pre-Christmas programme.
He was not expected to return until just before Christmas, but he has earmarked the Pro12 trip to the Scarlets on December 2 for his comeback.
Ulster presently have only one regular second-row available in Neil McComb, who will be involved on Sunday when Ulster travel to Zebre for the rearranged Pro12 tie.
