O’Mahony and Zebo return as Munster make four changes for the Ospreys

The big guns are back.

Munster have had a timely boost ahead of their Pro12 semi final against the Ospreys tomorrow, after captain Peter O'Mahony and Simon Zebo were both declared fit. The pair missed out on last week's bonus-point victory over the Dragins after picking up knocks against Ulster, but they represent two of four changes to Anthony Foley's side. O'Mahony returns at 6 with Billy Holland dropping to the bench, as Donnacha Ryan switches forward to the second row. Zebo's return means Ronan O'Mahony starts as a sub, having deputised for the Irish international last week. The other two changes come in the front row, as Stephen Archer and Dave Kilcoyne rotate for BJ Botha and John Ryan, while Duncan Casey makes a return to the bench after missing the game against the Dragons with a back injury. Munster: Felix Jones; Keith Earls, Andrew Smith, Denis Hurley, Simon Zebo; Ian Keatley, Conor Murray; Dave Kilcoyne, Eusebio Guinazu, Stephen Archer; Donnacha Ryan, Paul O'Connell; Peter O'Mahony Capt., Paddy Butler, CJ Stander.
