ball hockey injury to right quadracept

hi there,i recently started playing ball hockey.A week ago while I was running my quad seemed to tighten and ristrict,it was painfull but it only tightened when I wanted to sprint.If I am jogging it doesn’t seem to bother it too much. I played again last night and once again when I was doing a light run it was fine, but I tried to sprint and it wrenched.How do I know whetherthis is a pull or a tear and how should I treat it. Thank-youkrista
