Racist tweeter Liam Stacey, who posted offensive messages on Twitter about Fabrice Muamba, has been jailed for 56 days at Swansea crown court.
The 21-year-old Swansea University student sent the offending tweets just minutes after Muamba collapsed on the pitch during a game between Tottenham Hotspur and Bolton.
Swansea University said it has its own disciplinary proceedings had not ended although Stacey will remain suspended.
A spokesperson said: "The student remains suspended from the university pending the conclusion of our disciplinary proceedings."
Among the comments on his Twitter feed, @LiamStacey9, were: "LOL. F*ck Muamba. He's dead!!! #haha."
Following the negative feedback and threats by prominent Twitter user and ex-Liverpool striker Stan Collymore to call the police, Stacey claimed his account had been hacked.
Magistrates were told he attempted to delete his Twitter account.
Stacey told police he had drunk a considerable amount of alcohol when he wrote the offending tweets.
He said: "I was at the bar when I heard what had happened to Muamba. I don't know why I posted it.
"I'm not racist and some of my friends are from different cultural backgrounds."
Stacey pleaded guilty at Swansea magistrates' court to inciting racial hatred and was said to be close to tears as he was told he could be jailed.
Magistrates heard he texted a friend and said: "I said something about Muamba that I shouldn't have and tweeted back to some people who abused me. Getting police on me now which isn't good at all."
Barts and the London NHS Trust and Bolton Wanderers Football Club said in a joint statement: "Fabrice Muamba remains in intensive care at the London Chest Hospital, where his condition is serious but stable.
"He continues to make encouraging progress in his recovery. He has been able to sit out of bed for a short time, watch television and has begun to eat.
"However, he will need to continue to be closely monitored by the medical team at the London Chest for some time.
"His family requests that he receive no more visitors for the moment, outside of immediate family and members of Bolton Wanderers Football Club."
