Scotland prop Moray Low is set to miss the rest of the season with a hamstring injury, according to Exeter coach Rob Baxter.
The Chiefs tighthead came off during last weekend's Challenge Cup win over Newcastle and underwent scans this week.
The scans confirmed that Low had suffered significant damage to his hamstring, and he is now unlikely to feature again this season.
It's a blow for Exeter, who host Northampton this week before next weekend's Challenge Cup semi-final against Gloucester.
"We’ve had the results of the scan back on Moray and he has got quite a significant hamstring injury. It’s going to be unlikely that he’ll feature again this season, which is very unfortunate for Moray," said Baxter.
"He’ll start on his rehab programme and we’ll work very hard on that and get him fit and running around as soon as possible.
"You want everybody fit and to be able to pick from as strong a squad as possible. I doubt many people are selecting from a fully fit squad, so we’re completely happy with the squad we’ve got here and you have to make allowances that players will get injured and it creates opportunities for some players and that’s what it’ll do."
