Miami Dolphins quarterback Tua Tagovailoa's concussion check is going to be investigated by the NFL Players Association, per NFL Network's Tom Pelissero.
Tagovailoa left Sunday's game against the Buffalo Bills late in the second quarter with what initially appeared to be a head injury. He took a hard hit from Matt Milano and got up wobbly before momentarily falling to a knee.
