PGA Tour golfer Bill Haas, NBC sportscaster Jimmy Roberts and former NHL defenseman Mike Commodore are some of the many who have tweeted out the hashtag #hopeforhollis with a green heart drawn on their hand.

According to his website, Hollis had severe headaches with double vision, nausea, and weakness, which led to a tumor being discovered by doctors on his brain stem.

Hollis was then diagnosed with Diffuse Intrinsic Pontine Glioma (DIPG).

The goal on the page is $100,000.
