Exeter have suffered another injury blow at scrum-half with Dave Lewis set to miss the rest of the season after having knee surgery.
Lewis joins Will Chudley, Niko Matawalu and Haydn Thomas on the sidelines, but fortunately for the Chiefs the latter is nearing his return.
“We were told from the first scan there was a chance the cartilage issue could be quite bad,” Exeter head coach Rob Baxter told BBC Sport.
“He’s had to have a significant amount of cartilage repaired, which becomes quite a major operation.”
Baxter currently has young pair Jack Maunder and Stu Townsend as his available number nines for their Anglo-Welsh Cup game against Wasps.
“I think Stu will be starting for us this week,” he told BBC Radio Devon.
“Hopefully Haydn will be back next week to back them up, and then we’ll probably keep our eye on the market just to see who is potentially available.”
