NASHVILLE, Tenn. — The Tennessee Titans released wide receiver Mike Williams before this afternoon's practice.

The Titans signed Williams, the 10th overall pick in the 2005 NFL Draft by the Detroit Lions, last Thanksgiving and told him after the season to get his weight and conditioning under control.

Williams weighed around 270 pounds when he signed with Tennessee and lost more than 30 pounds this offseason in an effort to salvage his career.

But conditioning, weight and endurance remained issues for the former University of Southern California star, who had unsuccessfully petitioned the NFL for early entrance into the 2004 draft.

Williams spent two seasons with the Lions, catching 29 passes for 350 yards and a touchdown. He was traded to Oakland during the 2007 draft, but the Raiders released him in October after he dropped a key fourth-down pass against the Titans in a 13-9 loss.

Meanwhile, the Titans signed former Wake Forest and New York Jets receiver Chris Davis.

Tennessee also signed kicker Jon Vaughn, who was in camp with the club last year, to fill in for Rob Bironas after he strained his groin Monday. Guard Eric Scott was waived to make room.
