The Newcastle midfielder accepts the charge
Colback didn't place bet on matches involving his own side.
The Magpies midfielder Jack Colback has this afternoon pleaded guilty to an FA charge related to betting of football.
The offence is alleged to have happened in March 2016, but it did not involve his current club Newcastle.
Colback will be hit with a £25,000 fine as a result.
The FA rules don't allow footballers to bet on any football match at any level either directly or indirectly.
The former Sunderland man isn't the first player to break rule E8 with Joey Barton also being found guilty a couple of months ago.
He is yet to score for Newcastle in 14 appearances this season, but didn't feature in the 1-0 defeat to Blackburn at the weekend.
The Toon face Hull in the FA Cup Quarter Final this week.
