Glasgow Warriors duo Ruaridh Jackson and Moray Low face a race against time to be fit for their side's Heineken Cup tie at home to Champions Leinster the weekend.
Fly-half Jackson and prop Low both left the field in the first half of the Warriors' defeat to the Scarlets on Saturday evening.
Jackson limped off at Parc y Scarlets with a hamstring injury, while Low departed with a knee injury.
Both players will be further assessed this week to find the full extent of their injuries but it could be a big blow to the Warriors as the top two in Pool 3 go head-to-head.
Glasgow sit in second, six points behind the reigning Heineken Cup Champions with two rounds of action remaining.
