Haynos immediately fell to the ground untouched coming off the line during an offensive play in the fourth quarter against the Falcons, leading many speculate a serious foot or Achilles' tendon injury had occurred. While specific details remain unknown, the injury does appear to be significant and Haynos has been on crutches and a boot since Saturday.

Originally signed by the Green Bay Packers as an un-drafted free agent out of Maryland, Haynos has spent nearly two full seasons with the Dolphins and has amassed 21 catches for 184 yards and three touchdowns in 23 career games. After serving as the team's No. 3 tight end for most of his rookie season, Haynos moved into the backup job behind starter Anthony Francisco and started eight games.

Initially assumed to retain the No. 2 job in 2010, the Dolphins shook thing up by re-signing veteran David Martin after a year away from the game. Unlike players like Kory Sheets, who was waived/injured earlier this month to clear a Dan Marino jersey on the 80-man roster, Haynos was not waived/injured for this season, as the Dolphins are already at tomorrow's new 75-man limit, after which time players placed directly on I.R. don't count toward the active roster.

Instead, the Dolphins are simply giving the league an opportunity to claim Haynos and take on his entire contract (a base salary of $470,000 in 2010) if a team is willing. Of course, this is unlikely given Haynos' lack of upside and the likely severity of the injury, but it's worth a shot on Miami's part. Even when he was not on the team last year and through the off-season and the start of training camp, three weeks into his second stint with Miami, the nine-year veteran is starting to remind everyone why.
