Thirty other people received burns at the match in the Democratic Republic of Congo.
Kinshasa daily newspaper L'Avenir said local opinion - known to believe in charms and spells - was divided over whether someone had cursed the team.
The two sides were drawing 1-1 in the match in eastern Kasai Province when the lightning struck the visiting team.
"The athletes from [the home team] Basanga curiously came out of this catastrophe unscathed," the paper said.
There was no official confirmation of the report - a rebel war affects much of the east of the country.
The first strike
In a similar incident at the weekend, a premier league soccer match in Johannesburg was brought to an abrupt end when lightning struck the ground.
Half the players from both teams - the Jomo Cosmos and the Moroka Swallows - dropped to the turf.
Several writhed on the grass holding their ears and their eyes. Spectators and coaching staff ran onto the pitch to help. Fortunately no-one was killed.
