The back-and-forth continues between the Rabbitohs and the NRL on the Latrell Mitchell saga

The star fullback's facing a one-match ban after he was pictured with a white powder - but can only serve the suspension while fit to play.

South Sydney have submitted the advice of three doctors to see if tomorrow night's game with the Roosters can count as such.

But the NRL have gone back to the club requesting more evidence of Mitchell's fitness - including an independent fitness test.
