2 p.m.: Add veteran center Steve Vallos to the list of players who have been summoned to Dolphins headquarters for a Monday audition.
Vallos joins Samson Satele and Daryn Colledge (see below) as players scheduled to work out for the team on Monday.
Miami is searching for a veteran who can help compensate for the loss of center Mike Pouncey, who is expected to miss between two and six regular season games after hip surgery.
Vallos, 30, has played in 59 games over seven seasons, with nine starts. He played two years in Seattle, two in Cleveland, and for Philadelphia, Jacksonville and Denver the past three seasons.
He appeared in 15 regular season games for Denver last season, according to NFL.com, but logged only nine offensive snaps, according to ProFootballFocus.com. But he was forced into action during the Super Bowl because of an injury to Denver's center.
