Philadelphia Eagles tight end James Casey exited last night’s preseason finale against the New York Jets after suffering a hamstring injury, according to Zach Berman of the Philadelphia Inquirer.

Casey sustained the injury during the first quarter of the game, after which he didn’t return. It concluded a disappointing preseason for Casey, who has battled injuries throughout training camp and only caught two passes for 10 yards over the team’s four exhibition games.

It looked like Casey was slated for a larger role with the Eagles after signing as a free agent from the Houston Texans. The tight end/H-back inked a three-year, $12 million agreement, and he seemed to be a dynamic option out of the backfield or lining up at tight end in head coach Chip Kelly’s system.

However, before he’ll be able to do much of anything, Casey must first get back to full health. He missed most of the spring after undergoing arthroscopic knee surgery. It’s unclear how long he’ll be sidelined by his hamstring ailment, but more should be known by the weekend.

Philadelphia is deep at the tight end position, as they are bringing back Brent Celek and welcoming second-round pick in the 2013 NFL Draft Zach Ertz.
