NFL investigates why Rams’ Keenum not tested for concussion

The National Football League said on Monday it was investigating why St. Louis Rams quarterback Case Keenum was not tested for a possible concussion despite new rules to show the league is taking concussions more seriously. When he was tackled by Baltimore Ravens' 300-lb (136-kg) defensive lineman Timmy Jernigan, Keenum immediately held his head before managing to get to his knees while game officials sorted out a penalty. St. Louis's backup quarterback Nick Foles put his helmet on and began warming up, but a wobbly Keenum managed to stand up and stay in the game.
