Eagles Injury Report: Chris Polk and Trey Burton sit out

The Philadelphia Eagles returned to practice on Tuesday and there are a few updates on the team's injury situation as they prepare to face the Seattle Seahawks this week. Keep in mind the Eagles run a light workout on Tuesdays.

Only three players were missing from practice.

Quarterback Nick Foles is still out with a fractured collarbone. Head coach Chip Kelly noted on Monday that Foles is healing normally but there is still no timetable for his return. A report from last week suggested Foles could be out longer than originally expected. Veteran passer Mark Sanchez will continue to start in the meantime.

Running back Chris Polk sat out of practice. Polk has dealt with a nagging hamstring injury throughout the season, but according to Jeff McLane it appears he should be OK.

Depth tight end and special teams contributor Trey Burton was also held out of practice. Burton reportedly had some hamstring tightness but will return on Wednesday.

Philadelphia's running back depth would be very thin if Polk and Burton had to miss time. Polk is the team's third string ball carrier behind LeSean McCoy and Darren Sproles. Meanwhile, Burton serves as an emergency running back. Rookie wide receiver Josh Huff would be the next man up in case of emergency. Huff has spent time with the running backs in position drills this season and he even took a carry late in the Eagles' win over the Dallas Cowboys. Huff used to play running back before converting to wide receiver at Oregon.

Elsewhere, Emmanuel Acho was seen back at practice. After practice, Acho said he expects to be ready for this week's game. Acho suffered a groin injury in Week 12 that caused him to be limited in practice heading into Philadelphia's Thursday game against the Cowboys. The Eagles only activated Acho in that game in case of emergency. He did not play a snap. If Acho can return, he will likely go back to splitting playing time at inside linebacker with Casey Matthews.

The Eagles will release their first *official* Week 14 injury report tomorrow on Wednesday.
