Leicester are set to be without second row Geoff Parling for two months as he continues to deal with concussion problems.
The England lock suffered a second concussion of the season in last week’s loss at Bath, and has now suffered five concussions in 11 months.
As a result he will be out until December, meaning that he will miss all of England November Tests as well as the start of Leicester’s European campaign.
It had already been revealed last week that Parling would be taking an extended break to work his way back from his concussion problems, but Tigers boss Richard Cockerill has since confirmed the time scale he faces.
“It is a concern for his health. Playing is secondary to Geoff’s health,” Cockerill had said last week.
“He had a concussion [during the November Test period], another at the end of the season and now he’s had two in very quick succession in pre-season and at the start of the campaign. The bigger picture is Geoff’s well-being more than playing.
“I don’t want any of our players out there with potential brain injuries from concussions or whatever it may be because that’s not right.”
