Louis Domingue was wearing a special mask during his start on Sunday night in honor of Hockey Fights Cancer month.

The Tampa Bay Lightning goalie donned a white and purple helmet complete with drawings and designs from children being treated at The Children's Cancer Center of Tampa Bay.

Domingue had the mask made for the Lightning's "Bolts Fight Cancer" Night, which will be Tuesday at Amalie Arena, but while drawing the start in place of Andrei Vasilevsky on Sunday, decided to break out the bucket.

On the special helemt, in addition to some children's drawings, were "I Fight For" cards, which featured some names of patients at CCC.

Written across the front of the helmet, below the facemask, is the word "LOVE" in all capital letters.
