"There are not many players I respect more than Arian Foster," Texans general manager Rick Smith said in a statement. "He maximized his opportunity as an undrafted college free agent and worked to become the most productive back in franchise history, and one of the most complete backs in the NFL during his tenure with the Texans. Arian has contributed much, and meant a great deal to the success of the franchise over the past seven seasons and we wish only the best as he continues his playing career."The all-time leading rusher in franchise history total of 6,472 yards and 54 touchdowns, Foster was due a $6.5 million base salary with a salary-cap figure of $8.95 million. "I’ve got 7 years of beautiful memories with teammates, staff and coaches I’ll never forget,” Foster wrote on Instagram. “Thank you all for being a part of this journey. People that I call friends and brothers have all contributed to the success of what we did on the field, and also to the person that I am off. With everything in me, I love and respect the men and women you are. You are a part of me for good. And to the city of Houston, I genuinely appreciate every ounce of love I’ve ever gotten.” Follow me on Twitter: @AaronWilson_NFL Aaron Wilson covers the Texans for The Houston Chronicle.
