Gloucester Rugby skipper Grieg Laidlaw has recovered in time from the injury he picked up in the Six Nations to take a seat on the replacements bench for the Challenge Cup clash with La Rochelle this weekend.
Fellow scrum half Willi Heinz is also fit to return and will captain the side when they attempt to become the first team to win in La Rochelle this season and secure a place in a third Challenge Cup final at Edinburgh's BT Murrayfield on Friday, 12 May.
Laidlaw, who last played for Gloucester in mid-January, is set to move to France next season when he joins Champions Cup semi-finalists ASM Clermont Auvergne. A second change in the back line from the side that beat Sale Sharks at Kingsholm last weekend sees Tongan international David Halaifonua replace Charlie Sharples on the wing
It will be Gloucester's fourth trip to at Stade Marcel-Deflandre in the Challenge Cup. They won there in 2002 (36-12) and 2010 (13-6), but were beaten 42-13 in the pool stages in December.
In the pack, Tom Savage comes in for Mariano Galarza while Jacob Rowan and Ben Morgan both return in the back row to join forces with new British & Irish Lion Ross Moriarty.
"We know the huge challenge that La Rochelle are going to bring having played them twice this season. When you look at their record, I think until last weekend they had 12 consecutive wins in the TOP 14 - that shows the quality of team that they have," said Gloucester director of rugby, David Humphreys.
"They've rotated throughout the competition but, whatever team they put out, they'll be unbelievably competitive. Our focus has been very much on what we've done over the past four weeks and we feel we're in a good place.
"We've been scoring some good tries and playing some good rugby. We're all very excited about going to La Rochelle as the underdogs and almost with much less pressure than previously."
Former Springbok scrum half Ricky Januarie will partner Brock James at half-back, while French No 8 Kevin Gourdon will be one of the home side's biggest dangermen. Ginatj French international prop Uini Atonio will lead the side in the absence of Jason Eaton.
