Denton moved to Leicester last summer from the Worcester Warriors and made six appearances for the club in the opening six rounds of the Premiership season before suffering the head injury in the win against Northampton Saints at Twickenham.

Speaking about the decision on Denton, Tigers head coach Geordan Murphy said: "It's not ideal and we've missed Dave in the pack after he had a strong start to his time at the club at the beginning of this season, but his health is paramount and we're not in the business of risking players' well-being.

"Ultimately, the decision was taken out of his hands by experts and he's disappointed to not be out there with the lads but understands the importance of the situation and his long-term health.

"He will continue to work with our medical staff, alongside strength and conditioning coaches, towards a return for next season for the club."
