FLANKER Matti Williams and wing Dean Hammond face long spells on the sidelines after suffering more injury woe.

The luckless pair were forced off in Worcester Warriors’ 57-14 thrashing of Enisei-STM in Russia two weeks ago with Hammond sustaining a blow to his left foot and Williams injuring his adductor.

Director of rugby Alan Solomons confirmed Hammond would be out for “roughly 12 weeks” and Williams would be sidelined for “six to eight weeks at least”.

“Dean has got Lisfranc injury which is similar to what Alex (Hearle) had, but I don’t think he is going to need an operation,” Solomons said.

“For a thing like that you are looking at roughly 12 weeks.

“Matti has an adductor problem which is also a long-term injury.

“He’ll be out for probably six to eight weeks at least.”

Hammond missed a chunk of last season after damaging his bicep in training. Following a long pre-season, the South African would have been looking to push for a starting spot.

But the 27-year-old had to come off in September’s season opener against Leicester Tigers due to a head knock and suffered another setback in Russia.

A groin problem forced Williams to miss the opening weeks of this term before making his comeback in the Premiership Cup defeat to Exeter Chiefs last month.

But the back-rower looked close to tears when he left the field at the Kuban Stadium after another injury blow.

“They have been unfortunate with injuries,” Solomons said.

“Both of them go absolutely flat out whenever they play or practise. But sometimes you just have bad luck.

“Our medical and conditioning staff all do an excellent job.

“Due to the nature of the sport you are always going to have injuries.

“But we are in reasonable health at the moment.

”Marco (Mama) is two or three weeks away but apart him, Matti and Dean almost everyone is available for selection which is really positive.”
