Cleveland Browns tight end Kellen Winslow Jr. reportedly injured his kidney and liver while attempting stunts on his high-powered motorcycle last month. He will undergo surgery today on the right knee he tore up in the accident.

Winslow, 21, tore the anterior cruciate ligament in his knee when he crashed his motorcycle into a parking lot curb at 35 mph. He was hospitalized for nine days after being thrown over the handlebars.

In his first interview since the accident, Winslow told the Akron Beacon Journal that he lacerated his liver and kidney, bruised his right shoulder and cracked a bone in his upper right leg in the crash, in addition to the torn knee ligament.

He said all of his injuries have healed except for his knee. He added he was aware that riding a motorcycle is listed as a hazardous activity in his contract.

"I'm grown. I still have to live my life," Winslow told the newspaper. "I did know the circumstances behind it, but I'm still learning. I'm young. You think you're invincible. You think nothing's going to happen to you. It was a mistake."

Yesterday, the opening day of Cleveland's minicamp, Browns Coach Romeo Crennel said Winslow will miss the entire 2005 season -- the first time the team has been allowed to reveal that information because of federal privacy laws. . . .
