PARIS (Reuters) - Italian prop Martin Castrogiovanni, under investigation for a foul-mouthed rant, was left out of the Toulon team to face Leicester in the European Champions Cup on Saturday.

Toulon said on Wednesday that they were launching an "internal investigation and could sanction the players if necessary" after Castrogiovanni and Delon Armitage's outbursts following last weekend's game against Leicester.
