Source: FB Polite to stay with Dolphins

After bouncing around the league as a dependable fullback, living with the fear of being cut, Lousaka Polite has officially found job security with the Miami Dolphins.

Polite agreed Saturday to a two-year contract extension worth more than $3 million, according to a source. The new deal will pay him $3.7 million over the next three seasons, the source said. He was scheduled to make $620,000 this year.

The 27-year-old Polite is now under contract through the 2011 season.

It shouldn't be a surprise that the Dolphins would give him a home. Bill Parcells had him on and off the roster from 2004 to 2006 when he was the head coach of the Dallas Cowboys. Parcells runs the front office of the Dolphins and signed him to a contract last season.

The 6-foot, 245-pound Polite was an undrafted player in 2004 after being a four-year starter at fullback for the University of Pittsburgh. Polite played 27 games for Parcells in Dallas and started three.

Last year, Polite played 11 games and started five. Unlike a lot of fullbacks in the league, Polite got a chance to carry the ball rather than just block. He had 23 carries for 85 yards.
