Rookie safety Anthony Levine has signed a three-year contract with the Green Bay Packers following a successful tryout, according to a league source.

Levine, who went undrafted out of Tennessee State, didn't receive a signing bonus.

A strong Pro Day workout boosted Levine's stock.

His three-cone drill (6.64 seconds), 20-yard shuttle (4.05) and 60-yard shuttle (10.97) would have ranked first for any safety that worked out at the combine.

Levine's fastest time in the 40-yard dash was 4.43 seconds, unofficially. And he bench pressed 225 pounds 19 times.

The 5-foot-11, 193-pounder also turned in a 35-inch vertical leap and a 9-6 broad jump.

Several NFL teams sent representatives to Nashville, Tenn., to watch Levine perform, including Green Bay Packers executive Reggie McKenzie.

Other teams that attended the workout: the New York Jets, Tennessee Titans, San Francisco 49ers, Cleveland Browns, New York Giants, Chicago Bears, Kansas City Chiefs and the Philadelphia Eagles.

The 5-11, 195-pounder registered 129 career tackles, five interceptions and two fumble recoveries.
