Manchester City and Argentina defender Martin Demichelis has been charged for misconduct in relation to betting by the English Football Association (FA) on Wednesday.
"It is alleged the player committed 12 breaches of FA Rule E8 concerning football matches between 22 January 2016 and 28 January 2016," a statement on the FA website said.
"He has until 5pm on 5 April 2016 to respond to the charge," it added.
It is however, not known if the charge relates to the 25 games he has played for City this season.
New rules which came into force at the start of the 2014-15 season state that players and coaches are barred from betting on any worldwide footballing activity.
If found guilty, the FA can fine or suspend the 35-year-old.
Man City are yet to react to the news.
