Exeter without Feyi-Waboso as Reffell returns for Tigers

Immanuel Feyi-Waboso was forced off after half an hour of Exeter's Challenge Cup semi-final defeat by Ulster [Getty Images] There are now just four rounds of the Prem season remaining so it is safe to say we really are in the business end of the campaign. Twenty points might separate first from sixth in the table but there are only seven points between fourth and sixth. Tantalisingly, this weekend's round of matches features three games where all six of the teams still in the fight for the play-off spots go head to head.

You can listen to coverage of all of the matches on BBC DAB and FM local radio, via BBC Sounds or the BBC Sport website and app. Gloucester v Sale (Friday) Gloucester and Sale are both looking for back to back Prem wins for the first time this season [Getty Images] Having earned a morale-boosting, much-needed win against Exeter in their last outing, Gloucester's George Skivington has stuck with almost the same line-up as the Cherry and Whites look to close the gap on Sale, seven points above them in the table. Hooker Seb Blake returns after missing the win against the Chiefs, while Lewis Ludlow drops out with injury and James Venter comes into the back row.

Sale have made four changes to their starting XV as they also look to record back-to-back wins away from home having beaten Harlequins in their last game. Joe Carpenter starts at full-back, Marius Louw comes into the centre and Hyron Andrews comes into a shuffled forward pack. Rob du Preez misses out with a hamstring injury ending a record run off 88 consecutive Prem starts.

Gloucester: Barton; Joseph, Llewellyn, S. Atkinson, Loader; C. Atkinson, Williams (c); Rapava-Ruskin, Blake, Clark; Alemanno, Thomas, Venter, Trenholm.
