CLEVELAND -- Browns tight end Kellen Winslow's injuries are much more serious than first thought, NewsChannel5 reported.

5 On Your Side Health Team Anchor Lee Jordan reported sources close to the Winslow story said the Sunday motorcycle accident left Winslow with a broken tibia and femur, the large bone in his thigh. His ACL was damaged, possibly torn and there are lacerations on his liver and kidney.

NewsChannel5's source continues to stand by the information.

One media outlet is even suggesting Winslow's football career is over, WEWS reported.

Winslow previously had two surgeries on the right leg the he broke last fall.

Re-Creating Accident

Meanwhile, officials in Westlake re-created Winslow's accident by duplicating the motorcycle's skid marks in the parking lot of Cuyahoga Community College. The test, which involved using a special device, was designed to help gauge Winslow's speed when he crashed his motorcycle Sunday night.

Winslow Riding Motorcycle Accident Reconstructed

WEWS reported police didn't have a bike similar to Winslow's, so a Channel 19 reporter, with nearly the same bike and tires as Winslow's volunteered to do the skid test. Police gave him the green light.

Westlake police repeatedly cautioned the rider to go slowly, so they could estimate Winslow's speed.

He ended up falling off the bike when attempting to stop. (See Video)

Officials said the reconstruction closely resembled what happened to Winslow.

"As everybody saw, you can see how easy it is to lose control on a motorcycle when you're braking," said Lt. Bill Eschenfelder of the Westlake Police Department.
