Here is a sampling of reaction to Brian Dawkins' announcement that he is retiring after 16 seasons in the NFL.

NFL comissioner Roger Goodell: "Congrats Brian Dawkins on a successful 16-year career. Great player, great family. More importantly, great man in community and locker room."

Broncos head coach John Fox: "Brian Dawkins is one of the best to ever play the game, a future Hall of Famer who changed the way his position is played. In many ways, he helped my job as a coach with his great leadership and preparation. He brought so much to the table and was such an enormous asset to our football team. His contributions go far beyond the wins, interceptions, sacks and Pro Bowls he accumulated during his career. Brian is the definition of class and is what you want in a leader. I know our players, coaches, fans and so many within the National Football League feel the same way. I competed against Brian for many years with the Giants and coached him once in the Pro Bowl, but to be around him every day for a season was truly special. I'm not sure there was a more respected guy in our building than Brian. He knows defense, he knows football and he knows what it takes to win. I've got the utmost admiration for him as both a player and person. It's been an honor and a privilege to coach Brian. Although I will miss the positive impact he had on our team, I congratulate Brian on a tremendous career and wish him and his family all the best going forward."

Former Eagles center Jamaal Jackson: "Respects to one of the best to ever do it. On and off field! I appreciate all the words of wisdom u gave me! #NFLGREAT #20"

Eagles cornerback Asante Samuel: "You have done great on and of the feild. True definition of a warrior and passionate player. God Bless! #halloffamer"

Former Eagles linebacker Ike Reese: "Thank you bro for being an example (pro, father, bro, husband) for all of us who were blessed to know you! #WEAPONX #ganggreen."

Former Eagles defensive end Hugh Douglas: "Man! It was a true honor playing with you.. I love you like a brother you taught me a lot. Brian Dawkins!! Played hard every time even in practice!!"
