Ospreys will take on Leinster.at Swansea's Liberty Stadium tonight in this PRO12 clash. Leinster have spent the bulk of the campaign at the top end of the table, but could be feeling the effects of a tough European campaign, which saw them play away at Toulon last Sunday. The Ospreys side will be in fighting form too though, eager to claim a place in the semi-final. However, they will still have Brian O'Driscoll to contend with here and no doubt he is only dying to add to his trophy haul before he hangs up his boots for good. G'wan the BOD. Kick off at 7.05pm.
