Bolton Wanderers midfielder Fabrice Muamba has retired from football, according to The Sun.
Muamba suffered a cardiac arrest during a FA Cup match against Tottenham Hotspur last March - his heart stopped for 78 minutes.
A source told the newspaper: "Fabrice is devastated as you can imagine".
The Guardian's chief football writer Daniel Taylor has tweeted:
Told that Bolton Wanderers are going to make an announcement about Fabrice Muamba in the next 30 minutes or so . . #BWFC
