Wakefield chairman Michael Carter has confirmed that Tim Smith has been sacked by the club.
The Australian half-back has been fired due to gross misconduct and bringing the club into disrepute.
On Wednesday, he was in court, where he was banned from driving for 28 months, and fined £900, for failing to provide a specimen.
The player was also fined £600 for careless driving at Beverley Magistrates Court. All charges relate to an incident in September where Smith and team-mates Kevin Locke and Reece Lynne crashed a car in Hull.
Locke was released by the club earlier in the week, although Lynne has been retained, and played against Sheffield last weekend.
“A letter was last night sent to Tim Smith and his lawyer saying we were dismissing him for gross misconduct and bringing the club into disrepute,” Wakefield chairman Michael Carter said.
