SCRUM-HALF Jonny Arr will replace the injured Francois Hougaard for Worcester Warriors' derby with Gloucester at Sixways on Saturday (3pm).

The long-serving number nine has recovered from concussion and will make his first appearance for Warriors since October as Hougaard misses out due an ankle issue.

Arr is one of three changes to the side that stunned Exeter Chiefs 6-5 last Saturday with Josh Adams and David Denton named in the starting line-up after their exploits in the Six Nations.

Wales ace Adams will start alongside Chris Pennell and Bryce Heem in the back three, while Ryan Mills and Jackson Willison form the centre partnership.

Scotland forward Denton joins the back row next to Sam Lewis and GJ van Velze while Darren Barry retains his place in the second row as Will Spencer continues to overcome his sickness bug.

Barry is preparing for his 50th club appearance alongside veteran lock Donncha O’Callaghan.

Ethan Waller, Jack Singleton and Nick Schonert start in the front row.

Gloucester make two changes to the side that started last weekend's win over the Leicester Tigers.

Both are injury enforced with Ollie Thorley and Willi Heinz replaced by Matt Scott and Ben Vellacott respectively.

And there are also two changes in the replacements as Callum Braley and Owen Williams come into the matchday squad.
