Billy Vunipola could make his return for Saracens as they face Ulster in the Heineken Cup quarter-finals on Saturday.
The No.8 suffered an ankle injury while playing for England in February and looked set to return later in the season but he was back in training this week suggesting he could be involved in Belfast.
Saracens boss Mark McCall said: “We’ll make a decision later in the week. If Billy plays it’ll be because he’s fit to play. We won’t take a risk with any player.”
