'Challenge' Star Nelson Thomas Reality TV Stars Donate ... After His Fiery Car Crash

MTV's "The Challenge" star Nelson Thomas' GoFundMe is getting some serious support after his car crash, and some of the donations are coming from fellow reality stars.

The charity campaign quickly picked up steam after going live earlier this week -- and reality TV fans will definitely recognize some of the names chipping in with funds. Nurys Mateo and Tori Deal, who both starred on "The Challenge," dropped $1K each ... while Mark Long and Corey Lay from the series also ante'd up donations.

Outside of Nelson's 'Challenge' crew ... Nicholas Maccarone from "Big Brother" chipped in $250, "Wild 'N Out" star Justina Valentine gave $500, as did Maria Menounos.

Zak Longo from MTV's "Are You the One?" gave $5K ... moving the campaign closer to its $200k goal.

As we reported, Nelson was injured in a fiery crash in Austin, TX earlier this month. Minnesota Vikings receiver K.J. Osborn and a few others were able to rescue him from the wreckage.

Nelson ended up in pretty bad shape -- he showed some of his cuts and burns from his hospital bed, saying he's doing better but has a ways to go.

The GoFundMe, organized by a friend of his, will go toward medical bills and any other expenses that might come up.
