Cologne, Germany — A referee in Germany's Bundesliga was found bleeding in his hotel bathtub following an apparent suicide attempt hours before he was due to take charge of Saturday's game between Cologne and Mainz.

The game was postponed when Babak Rafati was found in his hotel room earlier Saturday "after sustaining injuries with no sign of any involvement by a third party," Cologne police spokesman Andre Fassbender said.

"It certainly looks like (a suicide attempt), yes," Fassbender said.

German Football Federation (DFB) president Theo Zwanziger said Rafati's condition was stable but that he would need "intensive treatment" and be hospitalized for some time.
