Tyler Johnson centered Tampa Bay's top line at Wednesday's practice. He was flanked by wingers Martin St. Louis and Ondrej Palat, while Valtteri Filppula was between Alex Killorn and Nikita Kucherov. Teddy Purcell ended up skating with J.T. Brown and Nate Thompson. The Lightning have been shut out in two straight games, so changes were bound to happen ahead of Thursday's match-up against Ottawa.
