Italy flanker Mauro Bergamasco will miss the Six Nations clash with Ireland after receiving a four-week ban for punching Wales skipper Stephen Jones.
Bergamasco will also miss Stade Francais' Heineken Cup clash with Leicester
Jones required four stitches and suffered problems with his vision after being struck by a swinging arm in the first half of Italy's 23-20 victory.
Centre Gonzalo Canale will also miss the match with a thigh injury.
But centre Matteo Barbini, hooker Fabio Ongaro and flanker Josh Sole are all back in training after injury.
Bergamasco's suspension means he will also miss Stade Francais' Heineken Cup quarter-final against Leicester on 1 April.
The 27-year-old is free to resume playing on 9 April.
