The handling of Case Keenum’s concussion during the St. Louis Rams game against the Baltimore Ravens shows how far the NFL still has to go in its in-game treatment, but the team will not be punished by the NFL for allowing a woozy, wobbly Keenum to remain in the game late in the fourth quarter.

Keenum’s concussion was sufficient enough that he is not expected to start Sunday, ESPN’s Adam Schefter reported, with Nick Foles starting against the Cincinnati Bengals. Schefter first reported the concussion news.

The day after Keenum’s injury, the NFL announced that it would investigate how Keenum stayed in for the Rams’ final two offensive plays in spite of a protocol that now includes a spotter on high tasked with watching players for concussion signs and empowered with the ability to stop action. Keenum was in the game for a third-down fumble that led to the Ravens’ game-winning field goal.

Keenum was sacked with 1 minute, 10 seconds left, his head bouncing hard off the turf at the Edward Jones Dome. Reggie Scott, the Rams’ head athletic trainer, came immediately onto the field to talk to Keenum while officials discussed a penalty, which prompted confusion. The league held a conference call with head athletic trainers last week in an effort to further clarify its concussion protocol and ESPN’s Chris Mortensen reports that there could be discipline the next time there’s an incident.

The NFL Players Association is continuing its investigation into the matter.
