Newcastle United midfielder Joey Barton has lost his boot contract, it has been revealed.

The Sun says Nike have terminated his boot contract - worth an estimated £40,000 a year.

Nike cancelled the deal, believed to be over two years, when Barton was jailed in May after pleading guilty to assault and affray.

A spokesman said: "We have provision in all our sponsorship contracts that take into account any actions by an athlete that bring the brand into disrepute.

"While Joey is a talented footballer, we cannot condone or accept what he did.

"Back in May when he was found guilty, we immediately terminated his contract.

"We certainly have no plans to re-sign him now that he has been released."
