The Tampa Bay Lightning announced Friday that captain Steven Stamkos has been added to the NHL's COVID-19 protocol list, a day after he was unable to play in a 5-2 loss to Florida.

The Lightning had listed Stamkos as day-to-day with a lower-body injury. 

Stamkos tweeted Friday evening:

"Thx to everyone who has reached out. At this time we suspect a false positive test. Hopefully that’s the case, and I will be back on the ice in the next couple of days.

Until then I will continue to follow the NHL Covid list protocols."

The Lightning are on the road Saturday night against the Panthers.
