April 28th, 2015:
Houston Texans signed Chris Polk, RB. Philadelphia had originally placed a 2nd round tender on Polk, who was a restricted free agent at the time. Polk did not receive any offer sheets from other NFL teams; Philadelphia pulled the offer sheet prior to the April 24, 2015 deadline. When that occurred Polk immediately became an unrestricted free agent.
Polk signed a 1 year contract for the minimum salary of $660,000. The contract also includes 46 man active roster bonus paid per game, maxing out at $100,000. The amount of bonus pay per game is $6,250. Polk has an LTBE roster bonus for 14 games for 2015.
Polk will compete with Alfred Blue, Jonathan Grimes, and Ben Malena for the number 2 running back spot behind Arian Foster. Polk does have some kick off return experience, which included a 102 yard kick off return for a touchdown against Washington during the 2014 season.
**Update, per Texans PR department. Chris Polk will wear jersey number 32.**
