PHILADELPHIA (973espn.com) - Bryce Treggs had put himself in the conversation for the back-end of the Eagles' roster after returning from a knee injury that had the veteran receiver on the NFI list to start training camp.

Treggs, however, is now out again after an apparent hamstring injury during Philadelphia's 37-20 preseason setback in New England on Thursday night.

According to NFL Media, Treggs will likely not have an opportunity to bolster his case during the final two preseason games which could have the organization trending in a different direction.

The Eagles will likely keep five or six receivers and the top five look locked in on paper with second-year preseason star Shelton Gibson, joining the four perceived locks: Alshon Jeffery, Nelson Agholor, Mike Wallace and Mack Hollins.

Jeffery's health and Hollins' poor summer could shake things up somewhat but the battle for the sixth spot, if there even is one, has ebbed and flowed between possibilities like Treggs, Kamar Aiken, Markus Wheaten, Greg Ward and Rashard Davis.

Treggs, 24, is one of Philadelphia's fastest receivers and had two receptions for 23 yards against the Pats before pulling up lame down the left sideline trying to corral a potential big gain from Nate Sudfeld after creating significant separation from the defensive back.
