As usual, NFL teams are keeping a close eye on the free agent market, bringing in players for visits and tryouts as they prepare contingency plans in the event that they need to replace injured players or add depth. Aaron Wilson of the Baltimore Sun has the details on several of the latest workouts and auditions from around the league, so let’s round up the highlights (all links go to Twitter)….

• In the wake of Jimmie Ward‘s season-ending injury, the 49ers worked out a handful of defensive backs, including Dominique Franks, Drayton Florence, and Marcus Cromartie.
• Before they decided to sign safety Bacarri Rambo, the Bills eyed several other defensive backs as possible replacements in the secondary for injured cornerback Leodis McKelvin. Chris Clemons, Brandon Taylor, Stephon Morris, and Josh Bush also auditioned for the club.
• A trio of linebackers – Moise Fokou, L.J. Fort, and Jerry Franklin – worked out for the Saints.
• We heard previously that the Eagles took a look at a couple former starting quarterbacks, but that wasn’t the only position at which the team auditioned players. Philadelphia also tried out wide receiver Uzoma Nwachukwu and defensive back Roc Carmichael.
• In addition to bringing in Allen Reisner, who signed with the team’s practice squad, the Ravens worked out fellow tight end Ike Ariguzo.
