Kevin Everett is walking on his own at a Houston rehab center, the latest significant progress by the Buffalo Bills tight end in his remarkable recovery from a serious spinal cord injury.

"He doesn't have a full natural stride but, yeah, he's walking," a person close to the family told The Associated Press on Friday. The person spoke on condition of anonymity.

The person said Everett has been walking under his own power since his release from Memorial Hermann Hospital three weeks ago and is now an outpatient there. The person said Everett attends daily rehab sessions at a Houston-area home, and he walks to and from the facility.

Doctors initially feared he'd never walk again after what was described as a life-threatening injury while making a tackle in the Sept. 9 season opener against Denver. Everett was paralyzed from the neck down when he arrived at Buffalo's Millard Fillmore Gates Hospital and spent the first few days on life support.
