Ben Roethlisberger's days of looking like Tom Hanks in Castaway are OVER -- 'cause the Pittsburgh Steelers QB is back throwing on the football field ... and he's got a new look.
Remember, Big Ben went down with an elbow injury in 2019 ... and promised to not shave or cut his hair until he could throw a football again "like, a legit NFL pass."
Steeler fans (and Ben's wife) have gotta love the clip Roethlisberger posted on social media on Monday ... showing the QB finally getting back to work at 100%.
