The veteran defensive end is testing the open market for the first time in his career. The Broncos are in the market for pass rushers and Allen fits the description.
Allen, 31, was a 16-game starter for the Minnesota Vikings last season, finishing with 11.5 sacks and two forced fumbles. A remarkably durable and consistent player, Allen has finished with at least 11 sacks in each of the last seven seasons.
Here are some other notable free agents with visits lined up:
» Safety Jairus Byrd is visiting the New Orleans Saints, according to Rapoport. The Saints have freed up millions in cap space in recent days and could be poised for a big splash. Byrd is the No. 1 on ATL's free-agent tracker.
» Wide receiver Golden Tate is visiting with the Detroit Lions, according to Rapoport. The Lions have targeted Tate as they look to finally find a true complement to Calvin Johnson. The team has an opening at receiver after releasing veteran Nate Burleson.
» Rapoport reports that cornerback Charles Tillman is visiting with the Tampa Bay Buccaneers. Tillman has plenty of history with Bucs coach Lovie Smith in Chicago and could become Tampa Bay's replacement for Darrelle Revis.
» Tight end Jermichael Finley is visiting with the Seattle Seahawks, according to Rapoport. Finley has yet to be medically cleared after suffering a spinal injury last year, but should attract interest from multiple teams. Production at tight end has been an issue for Seattle. Rapoport later added that Jason Hatcher will travel to Seattle, while The Seattle Times reports the Seahawks will visit with Taylor Price.
» Cornerback Walter Thurmond is visiting the Jacksonville Jaguars, according to Rapoport. Thurmond thrived with the Seahawks in a starting role after Brandon Browner was suspended last year. The Seahawks-to-Gus Bradley pipeline is strong.
» Quarterback Josh McCown is visiting with the Bucs on Tuesday. He also has visits scheduled with the Texans and Jets, Rapoport reported. NFL Media's Rich Hollenberg later reported that the QB was at the Bucs' facility Tuesday night.
» Offensive lineman Anthony Collins is headed to Tampa Bay for a visit with the Buccaneers, Rapoport reported. This development could mean bad news for Donald Penn, who is due $6.75M this year, Rapoport said.
