Health Insurance Policy for High School Athlete?

Hi, my son plays on a high school club sports team. We are homeschoolers, and so not affiliated with the school district. We lost our insurance and so don't have the required policy for him to be able to play. (Long story; glitch in ACA's writing means we are not eligible for premium assistance and can't afford husband's work insurance.) I am shopping for a simple coverage policy so he can play (while we research other longer-term options for our family). I have been looking online for options for individual accident health care coverage, and am having a hard time distinguishing what is legit, and what is not. Does anyone have any experience with this sort of thing, to recommend a health ins. policy for an athlete? Thanks!
