Josh van der Flier is fit and available for Leinster's Pro14 play-off semi-final showdown with Munster this Saturday, while their opponents are confident both Joey Carbery and Keith Earls will start at the RDS.

Flanker Van der Flier looked like he'd miss the rest of the campaign after suffering a serious groin injury in Ireland's Six Nations win against France back in March.

He underwent surgery, and has since made remarkable progress, with Leinster today declaring him available for selection ahead of the derby.

"He looks good, he trained last week," scrum coach John Fogarty told reporters. 

"He'll be monitored through the week and hopefully he gets through his minutes in training and if that's the case he's due to be available for selection."

Jamison Gibson-Park [hamstring] is also in good health and expected to come back into training this week but Joe Tomane [hamstring] is out.

Meanwhile, Munster head coach Johann Van Graan is extremely optimistic that both Earls and Carbery will be available for the trip to Dublin.

Both players trained fully from the end of last week, and will continue to play a full part as the squad prepares for Saturday's crunch clash.

Carbery's hamstring problem flared up in the Heineken Champions Cup quarter-final defeat of Edinburgh at the end of March and he has not played since.

Earls was forced out of the Pro14 clash with Cardiff Blues a month ago after suffering a thigh problem in the warm-up.

Their inclusion would be a welcome lift for Munster, with Rhys Marshall [calf strain] also back in the frame.
