A final decision on Owen Farrell’s fitness ahead of Sunday’s game against Leinster will be made on Friday, Mark McCall has confirmed.

The Saracens fly-half returned from England duty with an injured quad and has been rated 50/50 to feature in the Champions Cup quarter-final in Dublin.

The fixture comes too soon for Billy Vunipola (broken arm) while Brad Barritt is available for selection despite undergoing surgery on a fractured cheekbone on Tuesday.

George Kruis (back) is expected to recover but forwards Michael Rhodes, Vincent Koch, Will Skelton and Calum Clark all remain out.
