FC Dnipro Dnipropetrovsk coach Myron Markevych says his midfielder Matheus is doing fine after collapsing during his side's Europa League final defeat to Sevilla.
Matheus, 32, fell to the ground with no other players around him in the final minutes of Wednesday's final at Warsaw's National Stadium on Wednesday (27 May).
Players from both sides frantically signalled for assistance as alarm gripped the closing stages of the game.
Footage later showed the Brazilian midfielder had suffered a clash of heads while in an aerial challenge.
"It looks like everything is alright with him," Markevych told the club's official website.
"He worked a lot on the pitch today so perhaps something went wrong, but I think everything is alright now."
Dnipro confirmed the player had been immediately rushed to hospital but was later released after being diagnosed with a 'fracture of the nasal bones'.
"Matheus needed the help of doctors. The injury was so severe that the Brazilian was immediately sent to the hospital," read a statement.
"He was diagnosed with a fracture of the nasal bones and a head injury. A few hours later, he rejoined the football team at the hotel."
Scenes of a player collapse evoke tragic memories for Sevilla, who lost Antonio Peurta to a fatal heart attack in August 2007.
The Andalusian side were heavy favourites to record its fourth Europa League success but were forced to come from a goal down after Nikola Kalinic gave the Ukrainians an early lead. Grzegorz Krychowiak levelled after 28 minutes before Carlos Bacca put his side in front just three minutes later.
Ruslan Rotan restored parity a minute before half time with a well-executed free kick, but Bacca again found the breakthrough in a gripping second half, drilling a well-taken shot home to ensure his side's place in the Champions League next season.
