Scarlets and Wales face an anxious wait on an injury to Rhys Priestland in the 22-16 Heineken Cup defeat at Exeter.
The Welsh province bowed out of the competition as their Pool Five hopes were dashed by five penalties from Chiefs kicker Gareth Steenson - and injuries to Priestland, flanker Aaron Shingler and prop Samson Lee compounded the hosts' misery.
Priestland had been expected to line up at fly-half for Wales when they set about defending their Six Nations crown early next year, but his participation is in doubt after he was carried off on a stretcher.
"He has got an Achilles injury," confirmed Scarlets head coach Simon Easterby. "We won't know the extent of that until he has a scan. But it didn't look good.
"Aaron Shingler suffered a groin injury and he's been carrying that for a couple of weeks. Hopefully he will come through but that didn't look great either.
"You can't give any side the start they had and we slipped off a couple of tackles and they scored a soft try and they scored a couple of points from our error and indiscipline.
"The second half was much better. We played a lot more tempo and we won the second half 10-6. When you give a side the start we did it was always going to be difficult to get back into the game."
Exeter coach Rob Baxter, by contrast, was delighted to guide his side to their first ever victory in the competition, saying: "Nice to collect some points and do it on the road against the Scarlets who have a fantastic Heineken Cup tradition.
"We came into the season saying we wanted to compete in the Heineken Cup and we did that pretty well in the first couple of games. The next thing on the line was to force a win. It wasn't the greatest game of rugby but I think we did enough to win the arm wrestle."
