Was about to smash an overhead and my racquet slips out of my hand straight into the ground and I was like sheeetttttt, looked around and found the crack. My overgrip was really worn out and I kept saying I would get a new one but procrastinated and this is what I get I guess. Is the crack bad enough that I need to get a new racquet or can I still use it? I played with it fine after the crack but was just wondering since I heard the inside of a racquet can be poisonous??
