Ospreys lock Ian Evans' leg injury will be examined by the regional and Welsh Rugby Union medics on Monday.

Evans, 25, received lengthy treatment on the field in their 22-10 loss in Munster and played on until replaced by Ian Gough in the 33rd minute.

It was the latest in a series injuries to strike the lock who won the first of 16 caps in 2006 in Argentina.

Evans returned from a chest injury in January, having previously recovered from cruciate knee ligament damage.

He suffered that latter injury in Wales' autumn 2008 defeat by New Zealand and suffered the chest injury - tearing a major tendon in his chest - playing for Swansea against Pontypridd in October, 2009.
