The Steelers, who have been leaning heavily on DeAngelo Williams since Le’Veon Bell went down for the year, worked out former Rams and Jets running back Daryl Richardson, according to Aaron Wilson of the National Football Post (Twitter link). It doesn’t appear Pittsburgh will sign Richardson at this point, but it’s worth keeping an eye on the free agent market, considering Jordan Todman and Fitzgerald Toussaint – Williams’ current backups – have combined for just four carries this season.

Here are more workout notes from Wilson:

• The Broncos had a huge group of players in for tryouts this week, and Wilson (Twitter links) has the full list:
  • FB Ray Agnew
  • TE Brandon Barden
  • DT Alex Bienemann
  • TE Cameron Clear
  • WR Jace Davis
  • WR Antwan Goodley
  • WR R.J. Harris
  • C Alex Hill
  • T Cameron Jefferson
  • WR Jordan Leslie
  • QB Seth Lobato
  • WR Levi Norwood
  • QB Bryn Renner
  • T Jack Rummells
  • WR Demetrius Wilson
• Tight end Rob Housler was part of the Bears‘ latest workout group, which also featured tight end Nick Kasa and wide receiver Marcus Lucas, according to Wilson (Twitter link). Chicago’s starting tight end, Martellus Bennett, is expected to return to action this weekend, so I wouldn’t expect the team to add another player at the position.
• The Cardinals auditioned linebackers Josh Francis, Quayshawn Nealy, Markus Pierce-Brewster, and Mike Reilly, along with cornerback Jalil Brown, tweets Wilson.
• In addition to working out offensive tackle Pierce Burton, who signed to the team’s practice squad, the Colts also took a look at defensive end Nordly Capi and defensive back Terrance Mitchell, says Wilson (via Twitter).
• The Raiders tried out safety Dewey McDonald, tweets Wilson. McDonald was signed by the Patriots last week, but only lasted two days on New England’s roster.
