Source: Jamar Chaney ran a 4.45 today

Mississippi State linebacker Jamar Chaney lived up to his reputation for speed during his Pro Day workout today.

According to a league source, Chaney was clocked between 4.45 and 4.48 seconds in the 40-yard dash on NFL scouts' stop watches.

Following the workout, the Oakland Raiders conducted an extensive interview with the former Bulldogs standout.

Chaney was the fastest linebacker at the NFL scouting combine with an official time of 4.54 seconds ahead of Florida State linebacker Dekoda Watson's 4.56.

Chaney was "tremendous" in positional drills, per our source.

The Cincinnati Bengals and the Raiders sent their linebackers coaches to the workout, which was also attended by the New York Giants, Tampa Bay Buccaneers, Indianapolis Colts, St. Louis Rams, New Orleans Saints, Seattle Seahawks, New England Patriots and the Baltimore Ravens.

Chaney, who was the South team's Most Valuable Player on defense at the Senior Bowl, has also drawn interest from the Jacksonville Jaguars, San Francisco 49ers and the Miami Dolphins.

Chaney missed the 2008 season with a broken leg, but the 6-foot-1, 241-pounder started 39 career games.

At the scouting combine, the Florida native also bench presssed 225 pounds 26 times and turned in a 39-inch vertical leap.
