Club president Ibrahim Kizil told Turkish media outlet Sporx, "Unfortunately I can confirm that the news of suicide is true."
"His team-mates were concerned after he didn't participate in today's training session,” he added.
"He was in good spirits, he didn't seem to have any problems. I really don't understand why he did such a thing," said Kizil.
Gaziantepspor manager Bulent Uygun said: "We did not expect such a thing. All my players are in shock. Everybody is shedding tears."
The Czech Football Association sent its "deepest condolences to all his relatives" in a statement.
His former club also paid tribute to their ex-player, saying: "Rest in peace Rajt, we will all miss you so much, we will never forget you."
