Tutu Atwell concussed?

Rams WR Tutu Atwell left Sunday's game vs. the Ravens to be checked for a concussion. We haven't seen it confirmed that Atwell is in the protocol, but he likely is after not returning to the game. Atwell's absence helped lead to a whopping 10 targets for WR Demarcus Robinson. He caught three for 46 yards and a score. With a Week 15 matchup vs. the Commanders on tap, Robinson could be in play as a deep-league fantasy play if Atwell is out.
