In figures released by the NFL on Friday, a total of 281 concussions were diagnosed during the 2017 season.
Per Michael David Smith of Pro Football Talk, that number represents the highest total since the league began tracking concussions six years ago.
David Smith did note the biggest increase for concussions came outside of game action, with 45 occurring during preseason practices and 11 during regular-season practices.
The 179 concussions that occurred in regular-season games and 46 during preseason games were up from last season, something NFL chief medical officers Dr. Allen Sills said the league will try to combat in 2018.
