Isaac Boss could be a game changer for Leinster
The official word from Leinster is Eoin Reddan will be okay to start from a blow to the head last Friday night.
The more relevant issue is ... will he start?
The way Conor Murray and Reddan played in tandem worked well for Ireland in the Six Nations, the latter's tempo taking Ireland into a higher speed gear.
However, Reddan's poor box-kicking was a feature of Glasgow building an almost unassailable lead at The RDS last Friday night.
It was simply not good enough or else a poor tactical choice when Stuart Hogg is loitering with intent.
The impact of Isaac Boss off the bench was immediate and transformative, the New Zealander poaching two tries through sheer opportunism and will-power.
"It is a bit different when you're coming on around half-time and you're fresh compared to the 30-odd guys who have played 35 minutes," said Boss.
"That is the luxury of a reserve. Any reserve that comes on should be able to change the tempo of a game a little bit because of fresh legs."
The selection of Boss would enable Reddan to resume the role he has perfected for Ireland in the six Nations, not that the Limerick man would want it.
Either way, Leinster are at the business end of the season, still fighting on two fronts.
They cannot afford to be as slack exiting their 22 as they were against Glasgow or they will be made to pay the heaviest price by Bath.
"It is important that we've got enough guys in there that know the drill at this time of the year," he offered.
"It comes down to actually putting a performance together. We will remind ourselves of that.
"I am confident that we can go right to the end of both competitions.
"We've got the depth and we've got the talent and we've got the experience."
But, do they have the form?
