WORCESTER Warriors have made four changes to the starting line-up for their final Aviva Premiership game of the season against Leicester Tigers at Sixways tomorrow (4pm).

Donncha O’Callaghan is recalled to the starting line-up as captain in the second row in place of the injured Chris Vui.

Phil Dowson will make his final Warriors appearance before retiring.

Dowson steps in for Sam Lewis, who has a nose injury, as the 35-year-old gets set for his final appearance before hanging up his boots to take up a career in coaching with Northampton Saints.

In the front row, loosehead Ryan Bower starts in place of the suspended Val Rapava Ruskin, while young tighthead Gareth Milasinovich is also given the nod.

Cooper Vuna, Ryan Lamb and Ryan Grant are on the bench in what could be their final appearances for the club before they depart this summer.

Warriors are chasing a first Premiership win over the Tigers since 2008.

Tigers have made one change to the starting team, with Peter Betham recalled in place of the injured JP Pietersen.

Betham starts on the wing, with the rest of the line-up retained from a bonus-point win over Sale Sharks in Round 21 at Welford Road last weekend.

Pietersen suffered an ankle injury during the second half of that win and joins Telusa Veainu and Maxime Mermoz among the sidelined players.

The forward pack remains intact, with England internationals Ellis Genge, Tom Youngs and Dan Cole in the front row..

Dom Barrow and Graham Kitchener continue as the lock pairing, and Mike Williams, Brendon O'Connor and Luke Hamilton in the back row.

Betham's elevation to the starting line-up means there is a call-up for George Worth among the replacements tas Tigers chase the points required to guarantee a place in the Aviva Premiership semi-finals.

Head coach Matt O'Connor said: "Sixways is a tough place to go and Gary Gold has made a big difference there already.

"We have a lot to play for, we have to be accurate in our work and we have to be good enough to go there and get what we need to finish in the top four."
