MORE: Gallen targets NRL in abusive tweet
A day after Gallen used the word 'c..nt' to describe some at the NRL, he took to Instagram on Friday to express his remorse.
" I would like to apologise to anyone I offended in my tweet yesterday and to anyone who took offence to the language I used. I realise in the position I am in this is unacceptable. Gal."
The apology will not save Gallen from a 'please explain' meeting with Cronulla officials upon his return from holiday in Hawaii.
The veteran forward is likely to cop a heavy fine for his tweet.
