After scoring two tries in his opening two games for the Neath/Swansea Ospreys, former Ulster star Tommy Bowe has been rested for his side’s trip to Glasgow tonight.
Not surprisingly, caretaker coach Sean Holley has rotated his all-star squad for what is his side’s third game in seven days.
The Ospreys, however, have already shown their title credentials with two comprehensive victories over Connacht and a weakened Cardiff on Tuesday night and currently head the table with nine points.
“We’re expecting a real test tonight,” said Holley. “Glasgow are always a difficult team to beat, especially at home as our record up there suggests with just the one away victory over them.
“There’s no doubt that it’s been a difficult week with three matches in seven days and the travelling to Ireland and Scotland thrown in for good measure, and it is providing a true test of our squad depth.”
Leinster, who entertain Edinburgh at the RDS tonight (7.30pm, Setanta Sports 2), make two changes to the starting line-up from the side that drew with Cardiff.
Stan Wright returns to the front row while Trevor Hogan starts alongside Malcolm O'Kelly in the second row with former Ulster star Ronan McCormack moving to loose-head prop.
In the backline, Ireland duo Luke Fitzgerald and Girvan Dempsey come into a new back three which again features Rob Kearney.
Brian O'Driscoll continues his centre partnership with Argentina captain Felipe Contepomi, with Jonathan Sexton again partnering skipper Chris Whitaker at half-back.
Shane Horgan and Isa Nacewa are named amongst a strong list of replacements alongside the likes of Cian Healy and John Fogarty.
“Edinburgh are a tenacious side,” said Leinster defence coach Kurt McQuilkin.
“They never say die even when it looked like at one stage that Munster were going to romp home at one stage. They’re typical Scots, they dig in and I would consider them one of the better scrambling teams in the Magners League.
“Still, Edinburgh were in it right until the end. They can turn any side over on any given day and they’re never down. I thought their back-row was one of their main strengths last year.”
Munster coach Tony McGahan makes just one change to his match day squad for Sunday's Magners League clash with Newport-Gwent Dragons at Musgrave Park.
John Hayes and Rua Tipoki are omitted with Denis Hurley returning to the squad.
Hayes is still not fully recovered from the bout of illness that forced his withdrawal on the morning of the game against Edinburgh.
