Rex Hadnot, a 6-2, 325-pound starting guard from the Miami Dolphins, is visiting the Steelers today as an unrestricted free agent.

Hadnot started all 16 games for Miami last season.

The Steelers have a dire need at guard after the loss of Alan Faneca to the New York Jets in free agency. Chris Kemoeatu will replace Faneca at left guard; Kendall Simmons starts at right guard but there's no other experienced guard on their roster.
