Monday's sports briefs

Police don't plan to recommend pressing charges against a Green Bay Packers player accused of sexual assault by two women who changed their statements during the investigation, the chief overseeing the investigation in Lake Delton, Wis., said Monday.

Police Chief Tom Dorner said he expects to forward the investigation's findings to prosecutors by Tuesday, but he thinks they would have a hard time proving a case.

"I think it's going to be a problem because there's too much information that contradicts between the alleged victims and the alleged suspect," Dorner said.

Officers were called early Saturday to a condo in Lake Delton where seven Packers players were staying during a charity golf event. The women initially told investigators they were sexually assaulted by more than one Packer while other players held them down.

After the players were questioned, the women changed their statements to say only one person assaulted them, Dorner said Monday.

Police cleared six players of wrongdoing and have declined to identify the seventh player, though the Milwaukee Journal Sentinel reported it was cornerback Brandon Underwood.

Stampede serves as wake-up call A stampede at a supposedly low-key warm-up match set off alarms for World Cup organizers as they reassessed their plans for keeping fervent sellout crowds in South Africa under control.

Hopes for a safe tournament remain high, officials said Monday. But the scary incident at a Nigeria-North Korea exhibition was a stark reminder of past stadium disasters, in Africa and elsewhere, that have been one of soccer's recurring and deadly legacies.

"This is like an alarm clock," FIFA President Sepp Blatter said. "This will not happen in any match of the World Cup -- you can be assured."

FIFA stressed it played no role in arranging Sunday's match at a small stadium in Tembisa, a black township near Johannesburg. Crowds seeking some of the 10,000 free tickets on offer twice charged the gates; a policeman was seriously hurt and 15 fans also were injured.
