Tua Tagovailoa is back slingin' the ball at Miami Dolphins' practice after suffering a concussion 13 days ago ... and while it's a step in the right direction, the quarterback is still in protocol.
The 24-year-old was spotted in Dolphins gear on Wednesday at the Baptist Health Training Complex ... wearing his helmet and throwing the football.
Marcel Louis of ESPN says the QB also launched a couple of deep passes 25 to 30 yards downfield ... which is great to see, considering the frightening sight after hitting his head against the Bengals in Week 4.
