Over the years, only a pair of players have ever worn the number 63 for the Tampa Bay Lightning and both only wore it for a short period of time. 

Tyler Johnson was the first to wear the number during his first recall to the NHL. In 14 games wearing the number 63, Johnson scored three goals and tallied a total of six points. The following season, when he became a full-time NHLer, he switched to the more recognizable number nine. Johnson would go on to become a key part of the "triplets line" alongside Nikita Kucherov and Ondrej Palat early in his career and raised the Stanley Cup with the Lightning on two occasions.

Johnson retired from professional hockey following a nine game stint with the Boston Bruins during the 2024-25 season.

The next, and most recent player, to wear the number 63 was the Lightning's seventh-round pick in the 2011 NHL Draft, Matthew Peca. Peca appeared in 20 games, split across two seasons, for the Bolts from 2016 to 2018. During that time, he scored three goals and seven points before departing the Lightning organization at the conclusion of the 2017-18 season and joining the Montreal Canadiens. 

Peca has since become a mainstay at the American Hockey League level, even rejoining the Syracuse Crunch for a short stint last season. He's currently set to join the Rochester Americans for the 2026-27 season.
