Ben Barba says he may never play rugby league again amid frustrations over the NRL’s delay in registering his contract with Cronulla.

The fullback is understood to have signed to play rugby union with French club Toulon as he serves a 12-week NRL ban for a second positive illicit drugs test this year.

“The NRL haven’t given me too much … I might never play the game again. It’s taken them three months and nothing’s been sorted out,” Barba told reporters outside his home on Wednesday.
