Wing wonder Shane Williams has been ruled out for two weeks after being stamped on the hand during the Neath-Swansea Ospreys' victory over Munster.
Williams' right hand was badly cut in the accidental collision but will miss Friday night's derby clash against Llanelli Scarlets.
'It's a blow to lose someone of Shane's ability, especially for a local derby but these things happen in rugby, it's not too serious,' said Ospreys coach Lyn Jones.
There was further bad news for the Ospreys, who are top of the Celtic League following their 34-17 win at St Helen's, with the loss of Samoan centre Elvis Seveali' for the next six weeks with a torn calf muscle.
