The video was posted on YouTube on the Buffalo Bills' official channel in late July."It was definitely frustrating," he said (01:21). "But, you know, after the first few days of feeling sorry for myself and going through, 'Oh my God, this is happening again,' or whatever it is, you get over it, and you start improving, and you just keep working to get back healthy."And, you know, just trying to look at it from a positive lens, you know, take some strain off my body for that time of the year. I was able to rehab slowly and do it at a real smart pace. So it was all positive. I mean, it was obviously frustrating in the moment, but I moved on relatively quickly.”The 30-year-old added that he felt good and healthy during his first full practice after missing spring and OTAs and has worked hard in the offseason. He is now focused on shaking off rust, fixing mental mistakes and handling first-day nerves while adjusting to a new team and season.
