The Philadelphia Eagles worked out four free agent players at the team's facility on Monday. There is no indication that the team plans to immediately sign any of these players. It could very well be that the Eagles are just doing their homework.

The players that the Eagles worked out include: tight end Cameron Clear, tight end Richard Gordon, center Brian Folkerts, and defensive end Gerald Rivers. A report from earlier on Monday tipped off the Gordon visit.

It's a little surprising to see the Eagles interested in tight ends considering the team is already three deep there with Zach Ertz, Brent Celek, and Trey Burton. It's not so surprising to see the team work out a free agent offensive lineman. The Eagles offensive line has obviously struggled this season, though they're coming off their best performance of the year in Week 5.

Here's a little background on each player:

Richard Gordon

28-year-old tight end who was originally a sixth round draft pick in 2011. More info here.

Cameron Clear

The 22-year-old measures in at 6-5, 278 pounds. Clear signed with the Steelers as an undrafted free agent following the 2015 NFL Draft.

Brian Folkerts

Folkerts signed with the New Orleans Saints as an undrafted free agent following the 2012 NFL Draft. Folkerts spent a combined 26 games on Carolina's roster in 2013 and 2014, but he never started.

Gerald Rivers

The 25-year-old Rivers measures in at 6-5, 249 pounds. He's bounced around practice squads and offseason rosters around the NFL since going undrafted in 2013. Rivers most recently spent time on the Giants' practice squad in early September.
