HELP!!! Found a baby gecko in my house.. With no leg.?

I'm not sure what to do.. I was walking out of my room and spotted it on the floor. I got a closer look and saw it didn't have a leg. Also there's this hard black thing on ithe stub (could be dried blood but I don't know).

If the blood has stopped, he should be fine.
