Ulster prop Justin Fitzpatrick is a major doubt for Ulster's Heineken Cup Pool 4 back to back games with table toppers Saracens, due to a hand injury suffered in an domestic accident.
The 38 times Heineken Cup capped loose head is due to see a hand specialist this week. The 1999 Heineken Cup champions could be without the former Ireland international for up to six weeks.
Ulster are due to face Saracens, who top the Pool 4 with 8 points, at Ravenhill on Friday, 9 December, before travelling to Vicarage Road for the return leg the following Saturday.
Fitzpatrick returned to Ulster this summer after a season with Castres Olympique.
