On the 31 Thoughts Podcast Elliotte Friedman reports (12:15) on a European rumor of a trade of Tyler Johnson being traded to Detroit for Henrik Zetterberg, who could be placed on long-term injury reserve.
Johnson cleared waivers in October, so one would have to believe that Tampa Bay would have to add in such a trade.
Zetterberg has one more season on his contract. He stopped playing in 2018 due to a back injury.
