The Ukrainian club pay tribute to "a wonderul person" in an official statement after the 25-year-old forward, on loan at Illichivets Mariupol, was killed in Donetsk on Saturday
The 25-year-old Brazilian joined the Ukrainian Premier League leaders in 2012 and was on loan at Illichivets Mariupol.
A statement on the Shakhtar website read: "FC Shakhtar regretfully informs that on February 8, 2014, the life of a footballer, Maicon Pereira de Oliveira, tragically ended. He died in a car crash in Donetsk.
"He was a talented footballer, an open and friendly guy. Maicon loved life and knew how to make it positive and bright. This tragic, untimely and absurd death took away a wonderful person from our ranks. Maicon was only 25 years old.
"It is a terrible bereavement for each of us. Shakhtar expresses condolences and sympathy to Maicon's family and friends. May he rest in peace."
Maicon moved to Ukraine to join Volyn Lutsk in 2009 and scored over 30 goals for the club, having begun his career in his homeland with Fluminense.
He also enjoyed loan spells with Steaua Bucharest and Zorya Luhansk either side of his switch to Shakhtar.
