Oakland Raiders QB Derek Carr (back) admitted that a back injury suffered in Week 4 did impact his play throughout the course of the season. ‘Injuries will never be something I talk about, especially during the season, but since it’s after the season, the [back issue] was one of those things that was there,’ Carr said. The fourth-year quarterback suffered three transverse process fractures and said he wanted to deal with the injury instead of using it as an excuse.
