PHILADELPHIA (973espn.com) - The Eagles rookie camp didn't produce a lot of churning on the back end of the roster but one tryout player was rewarded Tuesday when undrafted rookie guard Johnny Gibson got a spot on the 90-man offseason roster.

To make room for Gibson, a former walk-on at Arkansas, the Eagles released receiver Dorren Miller, who spent time on the practice squad last season.

Gibson, 6-foot-4, 319, joins a crowded field on the interior of the offensive line in Philadelphia further bolstered by the re-signing of veteran Stefen Wisniewski on Monday. Pro Bowl right guard Brandon Brooks is still recovering from a torn Achilles suffered in the divisional round playoff loss to New Orleans, however, and will not be a participant in on-field work this spring and perhaps deep into the summer.

When Brooks is healthy, Wisniewski projects to be the game-day interior backup but Wiz could fill in for Brooks as the starting right guard in offseason work. Second-year player Matt Pryor could also get a look there as well.

Gibson, meanwhile, is the third OG brought in by the Eagles as an UDFA this year, joining Webster State product Sua Opeta and Stanford's Nate Herbig. Meanwhile, Warrington native Ryan Bates of Penn State has been listed as a tackle by the Eagles but has OG/OT versatility.

Coach Doug Pederson also mentioned that Halapoulivaati Vaitai might also get some looks inside now that first-round pick Andre Dillard is penciled in for the swing tackle spot Vaitai has held since 2017.

Miller, a Carson-Newman alum, was on the bottom of a WR depth chart that added not only DeSean Jackson and second-round pick J.J. Arcega-Whiteside in the offseason but also brought back Greg Ward from the AAF and signed UDFA DeAndre Thompkins out of Penn State, as well as Marken Michel, the brother of Patriots star running back Sony Michel, and Carlton Agudosi.
