Primarily a special teams and inline blocking tight end throughout his career, Smith, 34, walks away after 149 combined appearances with the Bills, Raiders, and Falcons. He netted a career $23.6 million in earnings over 11 years in the league.

Blocking specialist Lee has played a third of the offensive snaps this season.

Smith's TD reception was a critical score in the Falcons' Week 3 win. For fantasy purposes it was notable primarily because it was a tight end touchdown that did not go to Kyle Pitts. Smith can continue to be left on the waiver wire. 

Smith is labeled as a tight end, but he's essentially a third offensive tackle when he takes the field. The 34-year-old will be Arthur Smith's run-blocking tight end while Hayden Hurst operates as the pass-catcher. Smith getting traded is a surprise, but the move does free up $2.25 million for Buffalo.
