Booker, 2 other rookies sign with Dolphins

MIAMI (AP) -Running back Lorenzo Booker was one of three draft picks to sign four-year contracts Thursday with the Miami Dolphins.

Booker, a former Florida State star, was the Dolphins' third-round choice. They also signed punter Brandon Fields and linebacker Abraham Wright, both seventh-round picks.

The Dolphins have signed four of their 10 draft choices.

With 2002 NFL rushing champion Ricky Williams unlikely to rejoin Miami, Booker is expected to back up starting running back Ronnie Brown this year.
