Source: Multiple teams contact Procter

Former Dallas Cowboys offensive lineman Cory Procter, who was released Monday, already is visiting Denver, according to a league source.

The Broncos aren't the only team to express interest. According to the source, multiple teams have contacted Procter, whom former Cowboys coaches Bill Parcells and Tony Sparano -- both now with Miami -- helped develop.

Rarely do experienced lineman that can play guard or center come available at this time of year.

Procter started only 13 games in five seasons with the Cowboys. Eleven of those starts came at left guard in 2008 for injured Kyle Kosier, whom Cowboys coach Wade Phillips tabbed Monday as the team's new backup center.

The Cowboys originally signed Procter from the Detroit Lions practice squad in November 2005.
