WORCESTER Warriors have been dealt a double blow on the injury front with the Samoan wing pair of Ed Fidow and Melani Nanai being ruled out indefinitely.

Director of rugby Alan Solomons confirmed that Fidow suffered a severe pull of the hamstring whilst playing for the Cavaliers on Monday night and Nanai "probably" requires surgery to his shoulder.

Solomons said: "Ed pulled his hamstring very severely playing for the Cavs."

Fidow has struggled for first-team minutes since his arrival in the summer and played mostly for the second-string outfit but now looks set for a lengthy period on the sidelines.

As for fellow Samoan international Nanai, Solomons confirmed that he is going to require surgery having been out of action for a number of weeks because of the shoulder injury he sustained in December.

He said: "Melani is probably going to have to have surgery on that shoulder. It’s been bothering him for a while now."

There is a fresh injury worry for lock Andrew Kitchener who has damaged his shoulder and is out of contention for the time being.

Solomons continued: "Andrew is out because he has taken bangs on his shoulders and he's now got bruising on the AC joint."

Scrum-half Francois Hougaard remains out of contention with a foot injury while wing Dean Hammond and prop Callum Black both remain a while off a return.

But there is some good news in the medical department concerning the likes of centre Ryan Mills, back row Sam Lewis and wing Tom Howe who are all ready for action again after recovering from their respective injury problems.

"Both of them are back now (Mills and Lewis)," Solomons said.

"Sam is absolutely fine, he has no fracture. Mills has recovered from that foot injury.

"Tom is also fine. He came through this week and practised yesterday so all is well and he should be good to go."

There were encouraging signs for a number of other squad members with Solomons expecting second row Justin Clegg and youngsters Alex Hearle and Ollie Morris to be back in the fold after the break following Saturday's Gallagher Premiership home clash with Wasps (3pm).

Solomons offered a positive update on the condition of Hammond who has been out since the November European Challenge Cup game in Russia against Enisei.

The winger is likely to be back by the end of March but if he "progresses better" could return more towards the middle of the month.

Hooker Niall Annett is unavailable for a lengthy period still while props Conor Carey (Achilles) and Joe Morris are both out for the rest of the season.
