Former Great Britain centre Keith Senior fears his career could be over following Crusaders RL’s shock withdrawal from Engage Super League.

The 35-year-old had signed a two-year contract with the Welsh club starting next season but that is now likely to be cancelled after a dramatic turn of events at the Rugby Football League's licensing announcement.

Crusaders had been expected to be awarded one of the 13 remaining licences to compete in Super League from 2012-14 yesterday but instead it was revealed the club had pulled out.

Owners of the Wrexham-based franchise admitted fears over the sustainability of the club in the north Wales town.

Senior immediately made his feelings clear via social networking site Twitter.

"Crusaders have just f***** me over what a b*****d joke, excuse my language I'm absolutely furious," tweeted Senior, who had seemingly committed the final seasons of his career to Crusaders after 12 years with Leeds Rhinos.

Senior, whose current season has been ended by a knee injury, later said: "Somebody could have phoned the players and done the decent thing, saying what was happening with the club.

"All of a sudden to find this out like that - I was just sat down and saw it on TV.

"I presume with it being a Super League contract it will be terminated but I will have to look into things.

"I will have to see what the situation is. My agent will be making some phone calls to see if there is anything else, otherwise I might just become a full-time gardener."

Crusaders had endured a turbulent three years since their admission to Super League in 2009, having relocated from their original base in Bridgend, changed owner and had a spell in administration.

Their withdrawal meant a reprieve for Wakefield Trinity Wildcats , who had been expected to be excluded after financial problems of their own and a failure to meet minimum stadium requirements.
