Thompson made his NHL debut Sunday vs. Boston and got one shot on goal across 14 shifts and 11:39 TOI but will return to Syracuse (AHL) Monday. The 21-year-old was returned to the minors as Erik Cernak (upper body) likely returns to Tampa Bay's lineup Tuesday.

Declan Carlile and Sean Day have both been reassigned to the Syracuse Crunch of the AHL, prompting the Lightning to recall Thompson and Emil Martinsen-Lilleberg. In 31 games with Syracuse (AHL), Thompson has 20 points (2G / 18A).
