Arkansas star running back Rawleigh Williams III decided his latest neck injury suffered playing football will be his last. Williams on Monday announced his retirement from the game he loves in a long letter penned for his school's website. "I'm moving onto the next chapter of my life," Williams wrote. "It's tough to not be able to play football anymore beacuse I've been playing since I was four years old. It wasn't something I wanted to do or planned on having to do so early. I've prayed, listened to my doctors, my parents and my gut. "It still doesn't seem real yet, but I really don't have a choice. I've dodged the bullet twice. I realize that at the end of the day I want to live a normal life and be around my family." Williams, who led the SEC in rushing during the 2016 regular season, averaged 5.6 yards per carry and picked up 1,360 yards with 12 touchdowns on the ground just one year after missing the 2015 campaign due to a neck injury. He was set to enter the 2017 campaign as one of the SEC's best offensive players, but a hit he took on what wound up being the final play of the Arkansas spring game -- it was called following his injury -- "shook" coach Bret Bielema, the program and his family.
