"He was both responsive and communicative according to the information I have received," said Magnus Ericsson, chairman of the Malmö MFF supporters group of which the 25-year-old is well known due to his work to stamp out homophobia within football.
The situation for the 25-year-old has gained a wide following on social media under the hashtag #KämpaShowan and the information over his condition emerged via Twitter during Saturday.
"His family is at the hospital with him. When they have something they want to say they will let you know," Magnus Ericsson said.
Ola Nilsson, director of neurosurgery at Skåne University Hospital in Lund, confirmed to the TT news agency that the man's condition was slowly improving.
Some 150 people took part in a "kippa walk" in support of the man in Malmö on Saturday with participants coming from other parts of Skåne and Copenhagen.
"It was sickening. The threat has become more tangible, real, concrete," said local Jewish community leader Barbro Posner to the Sydsvenskan daily.
Around 9,000 people have meanwhile signed up on social media for Sunday's demonstration against racism and fascism in Malmö.
"It looks like it is going to be a huge manifestation. With political events the figure should be fairly close to the number attending, but it depends on the weather too. There are people coming from several other cities," said Lars Flysjö, spokesperson for the organization Skåne against racism, which is organizing the demonstration.
The demonstration comes a week after the clash in central Malmö that followed a demonstration in support of International Women's Day. While exact details remain unclear, a fight broke out in the area that involved at least one knife and left four people with serious injuries.
The nationalist Party of the Swedes (Svenskarnas Parti - SvP) appeared to take responsibility for the altercation in a statement released on Monday, in which the party confirmed that its members had been involved. Several people with ties to the party are suspected of attempted murder in connection with the incident.
The event has caused a swell of concerned commentary, following as it does the trial against neo-Nazis charged with inciting a riot after the Kärrtorp stand-off between anti-racism demonstrators and members of the Swedish Resistance Movement.
