Leicester have been handed a boost after back-row Tom Croft was given the all-clear to return to rugby on a full-time basis following surgery.
The England forward, who has been eased back into action after recovering from a neck operation, is a key starting player at the Welford Road side.
While he is unlikely to feature in the Six Nations, this development is a boost to Croft's hopes of making the British and Irish Lions touring squad.
"Tom is now ready to play consecutive weeks for us," Cockerill told the Leicester Mercury.
"He has metalwork in his neck to hold everything together while it heals.
"What you don't want is the screws to be working loose and that's why he was only playing every other week, to control the amount of impact and vibration going through him.
"He's been doing that for two months and we have had no adverse reaction to that. He has looked more and more comfortable as he has played every week.
"He was scanned on Monday and his X-ray has been sent to the specialist, who is happy that it has healed enough.
"It will take months for it to be completely healed so we will still manage him, but Tom was looking good at the weekend and I am pleased for him, because it was a serious injury."
