The Philadelphia Flyers were without forward Joel Farabee last night and it seems like they might be without him for awhile. 

Reports now indicate that Farabee has lost a considerable amount of weight because of the illness he's battling. 

Brandon Sommermann of PhillyFanLife believes that Farabee has mononucleosis. 

Carter Hart lost five pounds when he was struck with mono back in 2017.

Of course New York Jets quarterback Sam Darnold of the NFL made headlines this past season when he had mono.
