What does injury mean to you? He had a tight quad, in an area that has troubled him before, he got it massaged for three minutes and came back on court. Most MTO's are for small things that you feel can hamper your game, they can't really do anything for you on court if you have something major, now can they?
If you have something big or which you feel could worsen if you play more, you retire from the match.
