(CNN) -- FIFA has imposed a worldwide lifetime ban from football on 41 players from Korea who became embroiled in match-fixing activities in their domestic league.
In another episode that underlines the fight soccer faces to rid the sport of corruption, the game's governing body extended a ban handed down by the Korea Football Association (KFA) in 2011.
Of those 41 players, FIFA have offered 21 who handed themselves in voluntarily a chance to return to the sport after a probationary period of between two and five years.
The charges relate to match-fixing in Korea's domestic K-League competition and in all but one case were centered on offering or accepting bribes to throw matches.

A FIFA spokesman told CNN: "The K-League first issued the sanctions, which were then extended by the KFA in summer of 2011 to have national scope, and then subsequently FIFA extended them to have worldwide effect.
"FIFA announced 10 sanctions in June 2012 having received the case files from the KFA, and a further 41 Tuesday. There could still be further cases to follow, but we're not in a position at the moment to make any guess on numbers.
"Of the 51 cases, only one was for betting, whereas all the others were either for giving, or accepting bribes to fix matches.
"Of these 51 cases, 15 went to an appeal and an additional three persons (two players and one coach) committed suicide during the course of the investigations.
"Some of the 51 people involved have also been the subject of criminal proceedings in Korea, including jail sentences."

The initiative will be launched in nine countries: England, Finland, Greece, Hungary, Italy, Norway, Romania, Scotland and Slovenia.
The 21 Korean players who handed themselves in voluntarily will also be required to put themselves forward for community service if they decide they want to return to the game.
A statement on FIFA's website explained: "These services include the provision of coaching classes for local football clubs for youth and adult players; involvement in and support of football for those with disabilities; and the support of ongoing and future domestic anti-match-fixing activities.
"Players who are subject to voluntary probation may produce monthly reports on their respective community service activities, accompanied by documentary evidence of their activity (written, photographic or video).
"The reinstatement of the respective player in football after the probation period will only be decided by the Korea Football Association (KFA)."
