PHILADELPHIA (973espn.com) -  The Eagles have officially placed a second-round tender on restricted free agent tight end Trey Burton, virtually ensuring that the 25-year-old will remain in Philadelphia for the 2017 season.

Originally an undrafted free agent out of the University of Florida, Burton is guaranteed $2.8 million under the tender and if another team wanted to sign him they would have to prepare an offer sheet that the Eagles would have the right to match. If Philadelphia decided not to match it would get a second-round selection in return.

Burton, the team's third tight end behind Zach Ertz and Brent Celek, is coming off a career year in 2016 with 37 receptions for 327 yards and is also regarded as a very good special teams player.

The Eagles attempted to sign him to a longer-term extension last year and will likely continue to try to do the same now.

In other free agent news, the team was tied to Houston cornerback A.J. Bouye on the opening day of the so-called legal-tampering period, according to a report from NJ.com as well as Denver backup corner Kayvon Webster, first reported by a Denver-area radio station and confirmed by an NFL source to 973espn.com.

The NFLPA also released its first official salary-cap report in advance of the new league year on March 9 and the Eagles have even less money to work with than first thought, $8,457,224 million to be exact.
