Leicester have handed their England and British & Irish Lions flanker Lewis Moody a four-week ban after he admitting striking an opponent.
Moody was due to make his first appearance of the season in Saturdays Premiership clash against Wasps.
But the Tigers convened an internal disciplinary hearing on Wednesday night after Leeds officials cited Moody for an incident during last Mondays A League game between Leicester and Leeds.
Tigers suspension means that Moody is sidelined until October 6, although he still faces a Rugby Football Union hearing in Coventry on September 20.
Moody will miss Premiership appointments with Wasps, Bath and Leeds, plus a Powergen Cup tie against Welsh regional side the Dragons.
He only appeared as a second-half substitute against Tykes A team, scoring one of Leicesters eight tries as they triumphed 53-22.
The RFU disciplinary panel, chaired by Richard Moon, will inevitably take Moodys club ban into account when considering the case later this month, but they could also impose their own period of suspension.
Moodys place in the Leicester starting line-up on Saturday will be taken by Brett Deacon.
Obviously, we would have liked to have had Lewis available, but Bretts had a superb pre-season and he is a more than capable replacement, said Tigers forwards coach Richard Cockerill.
