The latest is former New York Giants receiver Hakeem Nicks, according to ESPN's Adam Schefter.

Nicks, as you may recall, was once a star receiver for the Giants from 2009-13 and helped lead the franchise to a win in Super Bowl XLVI. Following the 2013 season, Nicks signed a one-year deal worth a maximum of $5.5 million with the Indianapolis Colts. That came after Nicks did not record a touchdown catch in 2013, but still finished with 896 receiving yards in 15 games.
But from there, Nicks' career would sharply decline as he recorded just 38 receptions for 408 yards and four touchdowns in 2014. The Colts opted not to re-sign him during the 2015 offseason, leading Nicks to sign a minimal deal with the Tennessee Titans.
He would later be released during final roster cuts before reuniting with the Giants on Nov. 15 of this past season on a one-year deal. Nicks appeared in six games and made seven grabs for 54 yards in 2015.
Thus far in the 2016 offseason, Nicks has drawn virtually no interest around the NFL, and this workout with Cincinnati is more than likely the Bengals just doing their due diligence to see evaluate the best receivers left on the market. At just 28-years-old, Nicks, in theory, should have enough left in the tank to be an effective receiver, but showed little to nothing to actually suggest that last season.
Former Tampa Bay Buccaneers and Buffalo Bills receiver Mike Williams also is working out for the Bengals this week. It's likely we'll hear of at least one more veteran receiver working out for Cincinnati this offseason, given how thin this position is at the moment.
