Damien Varley will lead Munster into their RaboDirect PRO12 semi-final away to Glasgow Warriors on Friday (7.35pm)  as part of a team that shows four changes.

Head coach Rob Penney welcomes back BJ Botha, who returns at tight-head after missing last week's defeat against Ulster following the birth of his baby daughter. 

Dave Foley and Paul O'Connell remain in situ in the second row, as do Sean Dougall and James Coughlan in the back row with CJ Stander the only change at 6.

Conor Murray returns to the starting line-up to partner Ian Keatley in the half backs, while Casey Laulala will earn his 50th cap for Munster when he lines out alongside James Downey in the centre. 

The back three sees winger Keith Earls make his first start since Munster's Heineken Cup defeat to Toulon, partnering Simon Zebo on the opposite wing while Felix Jones retains his place at full-back.

A speedy and successful rehab has meant Andrew Conway returns to the match-day squad after sustaining a sprained toe against Edinburgh.

Munster: Felix Jones, Keith Earls, Casey Laulala, James Downey, Simon Zebo; Ian Keatley, Conor Murray; Dave Kilcoyne, Damien Varley Capt., BJ Botha; Dave Foley, Paul O'Connell; CJ Stander, Sean Dougall, James Coughlan.
