Jack McGrath out of Leinster's clashes with Bath as Nick McCarthy injury poses selection problem
Leinster could be without Jack McGrath for the remainder of their European pool games after the loosehead prop had an operation on his hip last week.
The province face Bath back to back in the next fortnight, before a series of interprovincial games and the decisive pool games against Toulouse and Wasps in the New Year.
Cian Healy will start at the Rec, with Ed Byrne likely to be ahead of Peter Dooley for the bench slot having started last weekend. Leinster say McGrath could be out for between four-to-six weeks.
The good news for the province is the return to fitness Jack Conan, Rory O'Loughlin, Dan Leavy and Jordan Larmour who could all come into contention this week.
However, a foot injury suffered by Nick McCarthy could present a dilemma to Leo Cullen and Stuart Lancaster who may have to leave Scott Fardy or James Lowe out of their team with Jamison Gibson-Park pressed into service along with Luke McGrath.
Alternatively, youngsters Hugh O'Sullivan or Patrick Patterson could be involved in their first European game. Leinster can add two players to their European squad this week.
