Seems like he refused a reduced contract, so I would assume the others accepted maybe?
So the club wanted to pay him off for less than what his contract was worth, he wouldn't accept and they sacked him.
They might have shot themselves in the foot! You'd think that any decent lawyer could make the argument that 1. he wasn't driving and 2. They've kept 2 players on for the same offense. I'd be shocked if the other 2 have had to reduced their contract.
