Ospreys backs coach Gruff Rees says the club have no plans to rush Wales back-rower Justin Tipuric back following a blow to the head.
The British & Irish Lions flanker suffered the knock in Wales' 67-14 Six Nations win over Italy on March 19 and has struggled with mobility since.
Rees has revealed Tipuric's Pro12 campaign could well be over, as the club have no intention of forcing a return for the forward before he is 100%.
He said: "We're not even putting any thought process around when the next game for Justin can be.
"It may be we just sit tight and see the season out and get to the summer."
The injury set-back also puts in doubt whether Tipuric will be available for Wales' tour of New Zealand this summer.
