ARLINGTON, TEXAS - Miami Dolphins quarterback Matt Moore suffered a concussion in Miami's 41-14 preseason loss to the Dallas Cowboys, and must now undergo the NFL's concussion protocol program to return to practice.
The hit occurred late in the second-quarter when a scrambling Moore, who has served as Ryan Tannehill's primary backup since 2012, clearly began his slide at the end of a 9-yard run. Cowboys linebacker James Morris drove at Moore’s helmet, and hit Moore in the head with his shoulder. Moore's head violently bounced off the field turf and the nine-year veteran stayed on the ground for a couple minutes while Morris was flagged for unnecessary roughness.
