With Lyon’s club doctor tending to the stricken 26-year-old goalkeeper, a firecracker can be seen landing on the pitch and exploding near a gathering group of players from both clubs.
Lopes then appears to roll away in pain, while one of the medical staff crouches down clutching his leg.
Metz defender Guido Milán, who seconds earlier had tried to stamp out the small explosive in vain, can also be seen arguing with supporters behind the goal.
In an online statement, Lyon described the incident a “sad evening for football.â€
“We’ve witnessed a sad evening for football this Saturday at the Stade Saint-Symphorien in Metz,†it read.
“A firecracker was thrown by some spectators in the stand behind the Lyon goal, landing just near… Anthony Lopes’s face. The Portuguese international didn’t have time to get up before another firecracker landed between his legs,†it explained.
