Two Eagles starters returned to the practice Thursday, while another was missing from the field during warmups.

Tight end Zach Ertz was a limited participant in Wednesday's practice because of a hamstring injury, according to the team, and he was not warming up with the Eagles on Thursday. Media are only permitted to watch the first few minutes of practice. Ertz wasn't with the team during that time.

Meanwhile, cornerback Nolan Carroll was practicing for the first time since he suffered a concussion in Sunday's win over the Falcons. Wide receiver Jordan Matthews also practice Thursday, one day after sitting out with back spasms.

Head coach Doug Pederson said earlier this week Matthews' back injury will not impact his status for Sunday's game in Seattle. Carroll's presence on the field likely means he'll also play in Seattle, providing a boost to an ailing crop of cornerbacks.

The bigger concern here is with Ertz, who missed two games earlier in the season with a displaced rib. Ertz, 26, is coming off two of his best games of the year. He had a season-high eight catches for 97 yards against the Giants on Nov. 6 and followed that up with a six-catch, 55-yard performance against the Falcons.
