Riley Sheahan started the season off with Pittsburgh Penguins, who he was under contract with. In 49 games with the Pens, Sheahan recorded an underwhelming tally of 7G, 2A, for 9 points.
His poor play only lasted so long as he was dealt alongside teammate Derick Brassard to the Florida Panthers on February 1, 2019, in exchange for forwards Jared McCann and Nick Bjugstad (along with three other picks heading in FLA’s direction).
With the Panthers, Sheahan received time in the bottom six (notably on the third line) and started where he left off with Pittsburgh.
