Pablo Daniel Osvaldo has apologised to AS Roma teammate Erik Lamela for their bust-up on Friday night.
The two came to blows in the Stadio Friuli locker room after last Friday's 2-0 defeat to Udinese.
Osvaldo was fined 50,000 and suspended for this weekend's Serie A game with Fiorentina.
"I am so sorry for what happened, but these are things that ought to remain in the locker room and not reach the newspapers," he told Striscia La Notizia.
"In any case, I regretted it immediately after doing such a stupid thing. Erik is a lovely lad, not to mention a great player.
"It's all over now, we can turn over a new leaf."
