File-This Aug. 28, 2014, file photo shows Philadelphia Eagles' G.J. Kinne, left, being hit by New York Jets' Rontez Miles during the second half of an NFL preseason football game in Philadelphia. It was last December 18, and Miles found out he would be on the team's active roster for the first time all season. He had played in only one other game with the Jets, in his rookie season the previous year, so Miles was amped up. He hit the practice field before just about everyone else and got ready for special teams drills. One play in, he got tangled up with a teammate, who smacked into his lower right leg. Just a few hours later, he was in an emergency room having the leg operated on, praying it didn't need to be amputated. (AP Photo/Michael Perez, File)
