D-Day for injury doubts Zebo and O'Brien
Munster and Leinster sweat on stars
Fans of Munster and Leinster will learn at noon if their stars have won their fitness races ahead of the Easter weekend's season-defining European Champions Cup quarter-finals.
Johann van Graan is expected to name Simon Zebo in his Munster side to take on Toulon at Thomond Park tomorrow, but doubts persist about the availability of Rory Scannell and Andrew Conway for the sell-out clash. However, the Munster 'A' selection for today's British and Irish Cup clash with Leinster suggests all three may make it with Robin Copeland vying with Jack O'Donoghue for the back-row spot left vacant by injured openside Tommy O'Donnell.
Leinster have their own issues for their meeting with Saracens at the Aviva Stadium on Sunday, with Jack Conan, Seán O'Brien and Rhys Ruddock rated as major doubts.
With Josh van der Flier out with a long-term knee problem, that puts a strain on the province's famed back-row depth ahead of their clash with the reigning champions, but Leo Cullen will be able to recall a slew of Grand Slammers to his side including Johnny Sexton, James Ryan and Devin Toner.
Saracens have issues of their own, with all eyes on Mark McCall's No 10 selection with Owen Farrell rated as 50/50 after suffering a quad injury.
Alex Lowoski is on stand-by if the England and Lions star fails to make it.
