BACK-ROWER Marco Mama is facing another lengthy spell on the sidelines after suffering some internal bleeding in his troubled right leg.

Worcester Warriors boss Alan Solomons said Mama would be out for “about four to six weeks” but went to see a specialist today to get a clearer prognosis.

Mama underwent four operations in early May to repair his leg after being diagnosed with compartment syndrome, a condition that occurs when pressure within the muscles builds to dangerous levels.

A long recovery process followed before returning to full fitness ahead of the start of this Gallagher Premiership campaign.

But Mama has now been hit by an injury setback after hobbling off in the closing stages of last week’s 24-20 defeat to Exeter Chiefs.

Solomons said Mama had sustained “a bleed into the same leg” that he had injured previously and had already undergone a fasciotomy – a surgical procedure that prevents tissue death.

“We have got to wait and see with Marco,” said Solomons after Saturday’s 19-14 victory at Harlequins.

“The specialist has got to have a look at it and we will get feedback.

“But at the moment we are looking at about four to six weeks.

“He got a bleed into the same leg as before.

“The fascia has been removed but I am sure he will be fine.”

Centre Ryan Mills (shoulder), fly-half Duncan Weir (hand) and full-back Chris Pennell (leg) were also forced to miss the trip to Quins after picking up injuries in the loss to Exeter.

But Solomons was optimistic about the trio being back in time for Warriors’ next Premiership clash against Sale Sharks at Sixways on Saturday, November 30.

“The other lads will be back,” Solomons added.

“There is not anything that is a long-term worry.

Despite being without some of their key players, Worcester managed to overcome a 14-3 deficit to beat Quins at The Stoop.

Jamie Shillcock, who replaced Pennell, scored the decisive try and Lance, who came in for Weir, notched a 14-point haul from the tee.

“We have showed some depth in the squad,” Solomons said.

“We had to make some changes as Penns wasn’t available, Millsy’s shoulder wasn’t 100 per cent right and Duncan had taken some big knocks.

“But everybody who came in played really well.”

Warriors will now head into two weeks of European Challenge Cup action, starting with a trip to Russia to face Enisei-STM on Friday (7pm) before travelling to France to tackle Castres eight days later.

Solomons said would provide a “timely” break for his Premiership stars as he looks to ring the changes.

“It is a short turnaround so I will rest a number of players and rotate,” Solomons said.

“We leave on Wednesday night, travelling through the night and only get there on Thursday lunchtime.

“It’s quite a difficult trip so the group will definitely be freshened up.”
