Fabrice Muamba Pictured Sitting Up And Smiling In Hospital

Fabrice Muamba's fiancee has posted a picture of the recovering midfielder on Twitter.

Sent via Muamba's own account, it shows the 23-year-old player - who suffered a cardiac arrest 13 days ago - sitting up in his hospital bed and smiling.

Shauna Muamba said: "Fab wanted me to post this pic for you all and to also say thank you for such overwhelming support."

Medics at the London Chest Hospital have said the ex-England Under-21 international has made "encouraging progress" this week, after his heart stopped beating independently for 78 minutes a fortnight ago.

Muamba's fiancee tweeted on his behalf:

It was revealed the Bolton player also watched his team on Match of the Day last Saturday.

Bolton beat Blackburn 2-1, in what was regarded as a major six-pointer, with both teams lying just above the Premier League's relegation zone.

The Trotters however lost their rescheduled FA Cup quarter-final tie to Tottenham 3-1 on Wednesday.
