FLANKER Sam Betty returns to the starting line-up for Worcester Warriors' Greene King IPA Championship match at Cornish Pirates tomorrow (3pm).

Betty, who was a late replacement in last Saturday's 39-26 victory over Yorkshire Carnegie, faces his old club for the first time at Mennaye Field since leaving in 2011 and will be looking to build on the 17 tries he has scored in 17 appearances this season.

Tom Biggs also returns to the side for Warriors' penultimate game of the regular season in place of wing Sam Smith, while Andy Symons comes into the back line in place of Max Stelling at outside centre.

Charlie Mulchrone comes in at scrum-half to link up with stand-off Ryan Lamb, while winger Cooper Vuna and full-back Chris Pennell keep their starting berths.

In the forward pack, Ryan Bower replaces Val Rapava Ruskin in the front row with Niall Annett given the nod at hooker next to Nick Schonert.

Darren O'Shea gets a first start in the second row since February in place of Jonathan Thomas, who moves to the back row to partner Betty and skipper GJ van Velze as Warriors hunt a 19th win of the league campaign.

Youngsters Ben Howard and Stelling are on the bench along with James Percival, who could be set for a first league appearance since February.
