49ers' veteran guard Jonathan Cooper on the bubble as cuts loom

Guard Jonathan Cooper was the No. 7 overall pick of the Arizona Cardinals in 2013. After playing well in 13 starts last season with the Dallas Cowboys, the last thing Cooper envisioned when he signed a one-year contract with the 49ers in March was to play all four quaters in the team's final preseason game. While nearly all of the established veterans – and some of the young guys – merely watched from the sideline, Cooper remained on the field, playing with and against players at the bottom ends of the 49ers' and Los Angeles Chargers' rosters.
