There is an abundance of receivers available as Tuesday’s trade deadline approaches, and no shortage of interested teams, with clubs like the 49ers, Patriots, Lions, Ravens and Colts deep in the process of trying to land another pass catcher.

They are determining where there is the best value and what it would take to land players like Hakeem Nicks, Josh Gordon and Kenny Britt -- all recent high draft picks -- while less-established options like Jon Baldwin and Greg Little are also available, league sources said.

Furthermore, the Redskins have continued to shop tight end Fred Davis, league sources said, while the Jags would move tight end Marcedes Lewis -- though his hefty contract, weak production and injury history preclude it. According to some who have been in contact with the Browns, they believe Cleveland would entertain offers for emerging tight end Jordan Cameron as well as Gordon, though it would take a steep haul of picks and/or players to acquire them.

The Browns and 49ers have been among the most active clubs leading up the deadline, sources said. The 49ers have shopped guys near the bottom of their roster, like Baldwin and Nnamdi Asomugha, according to league sources.

Colts GM Ryan Grigson has been working the phones feverishly looking to see if he can replace top receiver Reggie Wayne, who was lost for the season, though he has already dealt his first-round pick and has salary-cap limitations as well. A source said the Colts pulling off a deal for a receiver was “not likely,” though they are exploring options.

The Ravens are also in a cap bind, and might not be able to do better than Britt to try to spark their anemic offense, given how cheap his contract is. The Titans had been seeking a third-round pick for him, sources said, but that’s expected to lower at the deadline.

Detroit has been seeking to add a receiver since this summer, even before Nate Burleson got hurt, but given the issues they have had in the past off the field, taking on character risks like Britt or Gordon is not in their plans, sources said.

Nicks would be the crown jewel and teams are trying to land him from the Giants. Other GMs believe New York could get at least a third-round pick, and possibly a second rounder, for Nicks, and several will be renewing efforts to land him following Sunday’s results (particularly if the Giants lose again). Several GMs contacted this week believed ultimately the Giants would trade Nicks if they could fetch a third-round pick that moves to a second-rounder should Nicks re-sign with the team that trades for him, and that level of compensation is not out of the question.
