The Eagles continued to tinker with the bottom of their roster Tuesday by signing offensive lineman Johnny Gibson and waiving wide receiver Dorren Miller.

Gibson, who is 6-foot-4 and 319 pounds, was a tryout player during the rookie minicamp last week and will play guard for the Eagles. He was a two-year starter at Arkansas, playing his entire senior season at right guard after playing right guard, right tackle, and left tackle as a junior. He also started five games as a right guard in 2016.

Gibson was a college walk-on out of Dumas, Ark. The Eagles now have five undrafted rookie offensive linemen on their roster entering next week’s OTA.

Miller was on the Eagles’ practice squad last season, but the Eagles have 12 wide receivers on their roster.
