LONDON -- A new photo of Fabrice Muamba has appeared on the Bolton midfielder's Twitter account, showing him sitting up and smiling, almost two weeks after his heart stopped beating and he collapsed during an FA Cup match.

The first photo of Muamba since his cardiac arrest shows a bearded Muamba dressed and seated, with a pillow for support. "Fab wanted me to post this pic for you all and to also say thank you for such overwhelming support," an accompanying message said.

The former England under-21 international has been in the London Chest Hospital since collapsing March 17 in a game against Tottenham. Doctors worked on Muamba for 78 minutes to get his heart beating on its own.

Muamba, 23, was talking to doctors two days after his collapse. This week, he began eating again on his own.
