Hugo Keenan and James Lowe set for injury layoffs for Leinster

Leinster have been dealt a double injury blow in their back-three with both Hugo Keenan and James Lowe set for a spell on the sidelines.

The pair picked up injuries during Ireland's final Autumn Nations Series game against Australia last week, with Keenan picking up a wrist problem and Lowe injuring his calf, the extent of which has yet to be determined.

"Hugo picked up a wrist injury in the Australia game at the weekend, so I think they're talking around four weeks, is what I'm hearing there," Leinster head coach Leo Cullen said, after naming his squad for Sunday's Investec Champions Cup opener against Bristol Bears.

"James has an issue with his calf, we're still exploring how long that will be. We'll probably know a bit more in the next week. He was talking to a few different people, trying to get the full assessment of what went on.

"He finished the game against Australia but that's cropped up at some point in the game. Neither of those guys have featured during training with us this week."

Cullen is hopeful Tadhg Furlong (above) could be available to feature within the next couple of weeks.

The tighthead remains out with a hamstring injury, which saw him miss all four of Ireland's games last month.

"He had a niggle going into camp. On his return to try and get back playing he had a setback there.

"He is on the road to recovery. It will be a couple of weeks, which is what I gather from him. That's a on a week-to-week basis, hopefully it's a little bit quicker," Cullen added.

The Leinster coach has picked Ciarán Frawley to start at full-back in Keenan's absence and Jimmy O'Brien in place of Lowe on the left wing.

To offset those injuries, Leinster have been able to draft Jordie Barrett onto their bench for Sunday's game at
