PHILADELPHIA - Greetings from Lincoln Financial Field, where the Eagles continue their preseason tonight against Carolina.

They will be a little thin at outside linebacker. The team announced earlier today that Phillip Hunt underwent surgery to repair a partially torn anterior cruciate ligament in his left knee. The Eagles did not say when he was injured or give a timetable for his return.

Hunt was one of the players trying to make the transition from defensive end in a 4-3 alignment to outside linebacker, along with Trent Cole and Brandon Graham.

Hunt became the fourth Eagle to endure an ACL injury since training camp began three weeks ago. Wide receivers Jeremy Maclin and Arrelious Benn, plus linebacker Jason Phillips, are all out for the entire year with complete tears.

Hunt's injury could give another outside linebacker such as Chris McCoy an opportunity to earn a spot on the regular-season roster.

Besides McCoy and quarterbacks Nick Foles and Michael Vick, here are a few other player to keep an eye on tonight.

1. Running back LeSean McCoy: McCoy is making his preseason debut after missing the first game with a minor knee injury. McCoy will likely only play a series or two. He figures to play a major role in the offense this season, considering coach Chip Kelly likes to run the ball much more often than Andy Reid did.

2. Tackle Lane Johnson: Johnson, the team's first-round draft pick, missed a couple of days of practice to be with his wife, Chelsea, while she gave birth to their son, David Jace on Saturday. Johnson played very well against New England last Friday.

3. Safety Earl Wolff: The rookie fifth-round draft pick got some reps with the starters in practice this week. Nate Allen is still listed as the starter, but Wolff should get a lot of playing time.

4. Long-snapper James Winchester: Veteran Jon Dorenbos will not play tonight after suffering a concussion against the Patriots. Winchester was signed after tight end Brent Celek botched the snap on a field goal attempt against the Pats.

5. Defensive end Vinny Curry: Cedric Thornton and Fletcher Cox were ineffective against the Pats. Curry played well against the backups and could move into the starting lineup with another solid performance tonight.
