With a regulation or overtime win, Vegas would have the same record as the Tampa Bay Lightning (31-11-3, 65 points through 45 games). Each team would have 29 regulation or overtims wins, but the Golden Knights would own the tiebreaker after completing a sweep of their season series with a 4-1 win at Tampa on Thursday.
Gallant coached the Panthers for parts of three seasons before being fired Nov. 27, 2016.
Vegas defeated Florida 5-2 at T-Mobile Arena on Dec. 17. Forward Jonathan Marchessault, who scored 30 goals for the Panthers last season, had a goal and two assists and former Panthers forward Reilly Smith had two assists.
The Panthers are playing for the first time since last Friday, when they lost 4-2 to the Calgary Flames.
