Newcastle midfielder Jack Colback has been fined £25,000 after admitting a Football Association misconduct charge for betting.
Colback was charged with a breach of regulations introduced in 2014 which prevent players and coaches from placing bets on any football activity worldwide.
A club statement said: "Jack Colback has been fined £25,000 after he accepted an FA misconduct charge in relation to betting.
"The Newcastle United player breached FA Rule E8 in respect of a bet placed on the result, progress, conduct or any other aspect of, or occurrence in, a football match or competition on 16 March 2016.''
Colback's offence came two days after Newcastle lost 1-0 at Leicester and four days before they drew 1-1 with his former club Sunderland as they fought desperately -- and ultimately unsuccessfully -- to remain in the Premier League.
However, it is understood the charge did not relate to a game which had any bearing on the 27-year-old's club.
Colback missed Saturday's 1-0 Sky Bet Championship defeat by Blackburn with an eye problem and it remains to be seen whether or not he returns to action in the EFL Cup quarterfinal at Hull on Tuesday evening.
