Scarlets head coach Simon Easterby has expressed concern after Rhys Priestland was stretchered off with an achilles injury against Exeter.
Priestland was forced to leave the field in the 63rd minute and appeared in substantial pain, with Easterby suggesting that the initial signs were far from promising. The Scarlets also lost Wales flanker Aaron Shingler to injury during the match.
"He [Priestland] has got an Achilles injury," said 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," added Easterby.
Despite a late comeback including a penalty try, the Scarlets fell short against Exeter after going behind in the first half.
"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," added Easterby.
"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."
