Parker played for Papua New Guinea against England last month
Wakefield Trinity Wildcats' new signing Jessie Joe Parker will not be joining them after all, after he did not turn up on time for pre-season training.
The Papua New Guinea centre, signed from Featherstone Rovers in September, was scheduled to report on 15 November.
But Wildcats chief executive James Elston told BBC Radio Leeds: "There are time constraints you have to stick to when you sign an overseas player."
Meanwhile Trinity have released forward Richard Moore, 29, by mutual consent.
Prop forward Moore, who joined the Wildcats from Leigh in September 2006, spent four years at the club, making 92 Super League appearances.
But his time on the pitch was limited after it became clear in 2009 that he was suffering from Crohn's disease, an inflammatory disease of the intestines.
"It was a mutual release," said Elston. "We've been good to him regarding sticking with him through his illness and other issues and he's been very good for us.
"But, if it meant his release would allow us to bring in more new faces, then we were happy with that too. In the end that was the option."
Most guys have been back since October training and we wanted everyone here at the latest by December 1

The departure of Moore and the 'non-arrival' of Parker frees coach John Kear to add two new names to his squad for 2011.
"We have two new signings we'll announce very shortly," added Elston. "They will be direct replacements for the out going players."
As for Trinity's close season signing Parker, the 24-year-old Papua New Guinea international agreed a two-year contract when he signed in September.
He played at centre for Papua New Guinea in the 36-10 defeat to England at the Four Nations tournament on 6 November - and was due to report to Wakefield the following Monday week.
But Elston said: "He has not been able to get in to the country under those guidelines at the right time, so we had to end it.
"It was due to a few administrative issues, not visas issues, but issues with the player himself failing to get the right paper work together in time.
"He was able to get into the country but not under our time scale. He couldn't meet our strict guidelines on getting to training when we wanted him here.
"Most guys have been back since October training and we wanted everyone here at the latest by December 1."
