A Bolton Wanderers striker has had his phone taken off him in a bid to curb his "obsession" with Twitter.
Fabrice Muamba admitted he is still "far away" from returning to a football pitch but remains hopeful he will be able to resume his career.
Fabrice Muamba spoke to ITV's Adrian Chiles about his 'miraculous' recovery from a cardiac arrest he suffered during a match.
Fabrice Muamba and wife Shauna have revealed they are expecting their second child, less than a year after the former footballer almost died on the pitch.
The couple, who married in October, already have a four-year-old son, Joshua, and are due to become parents again in June.
ShaunaMuamba wrote on Twitter: "Thanks for all the lovely well wishes @fmuambaand I are so happy. We've been so blessed and can't wait to meet our newbaby."
Muamba, a former England Under-21 international, was playing for Bolton in an FA Cup quarter-final against Tottenham in March when he suffered a cardiac arrest and collapsed.
The midfielder's heart stopped beating for 78 minutes but because of the prompt treatment he received on the pitch he defied the odds to survive and make an incredible recovery.
Muamba had hoped to resume his football career but was advised against it by doctors and retired from the sport in August.
In October he launched the Hearts & Goals campaign, which is aiming to increase the number of defibrillators available in public places and provide CPR training to try to reduce the 100,000 people who die of sudden cardiac arrest every year in the UK.
Muamba has also published a best-selling autobiography, I'm Still Standing, and is part of ITV's coverage of the African Nations Cup.
Fabrice Muamba has confirmed his retirement from football on Bolton Wanderers' website. He said in a statement:
Since suffering my heart attack and being discharged from hospital, I have remained utterly positive in the belief I could one day resume my playing career and play for Bolton Wanderers once again.
As part of my on-going recovery, last week I travelled to Belgium to seek further medical advice from a leading cardiologist. But the news I received was obviously not what I had hoped it would be and it means I am now announcing my retirement from professional football.
Football has been my life since I was a teenage boy and it has given me so many opportunities.
Above all else, I love the game and count myself very lucky to have been able to play at the highest level. While the news is devastating, I have much to be thankful for.
I thank God that I am alive and I pay tribute once again to the members of the medical team who never gave up on me. I would also like to thank everyone who has supported me throughout my career, and the Bolton fans who have been incredible.
I am blessed to have the support of my family and friends at this time.
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:
Fabrice Muamba admitted he is still "far away" from returning to a football pitch but remains hopeful he will be able to resume his career with Bolton.
The midfielder was at the town's Victoria Hall this morning to receive an honorary doctorate from the University of Bolton at their graduation ceremony. Muamba was presented with the award to honour both him and the doctors who saved his life when he collapsed with a cardiac arrest.
Speaking at the ceremony, Muamba said: "I'm getting stronger every day. I'm far away from being back on the football pitch.
"I really, really hope, by the grace of God, that I'll be back on the pitch but I'm just grateful to the university for this doctorate and I receive it on behalf of everybody who helped me to survive the cardiac arrest."

We are absolutely delighted that we will be able to welcome Fabrice and his family back to the Reebok, and we are all looking forward to seeing him.
It's fitting that the match is between these two clubs and that Fabrice is able to come along.
I know Fabrice is very keen to show his appreciation to both sets of fans for their support.
Fabrice Muamba is to attend Bolton's Barclays Premier League game against Tottenham on Wednesday night, his club have confirmed.
It will mark the first time the Wanderers midfielder has attended a game since he suffered a cardiac arrest in an FA Cup tie between Bolton and Spurs at White Hart Lane on March 17.
