[ESPN.com] Chiefs coach Todd Haley has apologized for refusing to shake hands with Denver Broncos coach Josh McDaniels after the Chiefs’ blowout loss on Sunday.

After the game, which the Broncos won 49-29, McDaniels ran toward Haley for the traditional handshake. But Haley pulled his hand away and pointed at McDaniels. He said something briefly, obviously angry, and then quickly turned his back.

Haley declined Monday to say why he was upset after the 49-29 loss.

Haley says he probably let the emotions of the situation get to him, adding, “And I apologize. I apologize to the fans and to Denver and to Josh.”

McDaniels’ Monday news conference began with several questions about the exchange and McDaniels said he still had no idea why Haley was upset with him. He said Haley hadn’t called to apologize or elaborate.
