Leicester Tigers' new signing Miles Benjamin faces up to four months out after picking up a neck injury in an A League fixture.
The winger has yet to feature for the first team after his summer move from the Worcester Warriors.
"Unfortunately, Miles suffered a pretty nasty injury to his neck against Northampton in the A League two weeks ago which has resulted in a spinal injury," read a statement.
"He will be potentially out for three to four months."
Tigers captain Geordan Murphy is to miss Saturday's game with Harlequins because of a knee injury.
