The Arizona Cardinals made a small change to the back of the roster on the offensive line. They released guard Christian Johnson and re-signed center John Estes.
Johnson was signed to a future contract back in January. He played three years in the Arena League.
Estes (6-2, 293) was previously signed by the Cardinals on March 4 before being released on May 12 when undrafted rookies were signed. He appeared in two games with the Jacksonville Jaguars after originally joining the team in 2010 as an undrafted rookie free agent out of Hawaii. He spent his rookie season on injured reserve before playing two games in 2011 with the Jaguars. Estes missed the 2012 season on injured reserve. While at Hawaii, Estes was a four-year starter and a three-time first-team All-WAC selection.
It is likely a move that is simply for movement at the back of the roster. Don't expect Estes to be anything but a camp body for now. It could mean that they have some injuries at center they want to cover.
Lyle Sendlein continues to be the starter at center and Tommie Draheim has been taking second team snaps from what I can recall.
