Jordan Larmour will return to Leinster training this week and could be in contention for the Heineken Champions Cup trip to Bath, but Jack McGrath is out for up to six weeks.

Larmour came off the bench to help Ireland to a historic defeat of New Zealand in Dublin but was released from camp ahead of the USA game. 

He has since had a "minor procedure" on his knee, according to the province, and will come back into training ahead of the European clash.

Dan Leavy meanwhile is being closely watched as he steps up his recovery from a neck problem. The flanker missed out on the win against the All Blacks. He had been named to start but failed a late fitness test having struggled with what the IRFU described at the time as "general tightness".

Leavy will increase his training load as the week progresses.

McGrath will completely miss a busy December however. He's had a procedure on his hip and is expected to miss the next four to six weeks.

Jack Conan is also nursing a shoulder injury but Leo Cullen will hardly be light on options.

Rob Kearney, Johnny Sexton, Tadhg Furlong, Devin Toner, James Ryan, Josh van der Flier and Sean Cronin all come back into the fold after getting a breather post the All Backs game.

Leinster hammered the Dragons on Saturday evening despite fielding what was effectively a second-string side.

Dave Kearney, Jimmy O'Brien, Scott Penny, Scott Fardy, Caerlan Doris, Hugo Keenan and Bryan Byrne all crossed the whitewash in a 59-10 rout.
