The Australian goalkeeper had told the told the Premier League tribunal that Chelsea had acted improperly in the way in which they dismissed him following his positive drugs test for cocaine in November last year.
Bosnich had claimed he only failed the drugs test because a drink had been spiked without his knowledge?!
However a statement released by the Premier League this evening (Tuesday) has ruled in favour of Chelsea.
It said: "In the matter of the appeal from Mark Bosnich against the notice to terminate his contract issued by Chelsea FC, the board of the Premier League have found in favour of the club.
"Mark Bosnich has the right to appeal against this decision to the Football League appeals committee within seven days. Any appeal must be heard within 14 days of receiving the request."
If Chelsea had failed in their case against Bosnich, the club would have been liable for at least his back pay – more than £300,000.
The hearing began last Thursday and concluded the next day at the Premier League's London headquarters.
Of course Bosnich’s troubles don’t end there - he is yet to face a Football Association disciplinary hearing folowing his positive drugs test.
