Argentina football great Diego Maradona reportedly collapsed after watching his former team beat Nigeria in a tense clash at the FIFA World Cup.
A video clip posted on Twitter shows a man was helping Maradona stay on his feet as he was led away from his seat overlooking the pitch and into an adjacent room.
The footage was posted by Fernando Schwartz, a well-known sports journalist in Mexico.
A photograph also posted on Twitter appeared to show two medical staff attending to Maradona.
The Argentinean website of sports broadcaster ESPN said Maradona was taken to hospital but newspaper La Nacion said he was treated for low blood pressure in the stadium and was able to leave the stadium normally shortly afterwards.
Maradona, who led Argentina to the 1986 World Cup title, has battled cocaine addiction in the past.
A late goal by Marcos Rojo gave Argentina a dramatic 2-1 victory over Nigeria in Group D which sent the twice champions through to the knockout stages of the World Cup.
