Toulon hope Jonny Wilkinson will be fit for their Heineken Cup semi-final against Munster following injury in their 29-14 victory over Leinster.
Wilkinson was forced off in the 28th minute after suffering a recurrence of a hamstring injury.
Reigning European champions Toulon went on to beat three-time cup winners Leinster in the quarter-final clash at Stade Felix Mayol and will face Munster in Marseille on 27 April for a place in the final.
Toulon assistant coach Pierre Mignoni said: "Jonny has aggravated the same hamstring as before but it didn't look too serious.
"Hopefully he'll be OK and back in one or two weeks but we have to wait and see."

Wilkinson kicked Toulon 6-0 ahead but Leinster's Jimmy Gopperth levelled the scores by half-time with two penalties.
However Xavier Chiocci and Drew Mitchell both scored second-half tries while Matt Giteau kicked ten points to steer the holders through.
Delon Armitage also kicked a penalty while brother Steffon was named man of the match following a dynamic display.
Mignoni added: "We made a lot of handling mistakes in the first half that put ourselves into tight spots at times but we were still dominating the game and we knew that victory was in our reach.
"Of course we were disappointed to lose Jonny early but we always had confidence in the players available."
