can anyone identify this spider?

Je
Awful picture I know, but this is the third type of this spider I've caught in my room this week! This one has been the smallest of the 3 (the first was scarily huge). 
It's really fast,
Sorta brown with a bit of black part on it's body. 
Has a bit of a leg (issue? Maybe idk) on one side. Basically all the spiders look like one side of legs have been disfigured. 
I can't tell if it's like defensive spray because or poo but they let that out... 
Please help!
