Rib Protector for my nephew

[Techsas Tech]

Anyone know of a good upper rib protector or has had any experience with one? My nephew is transitioning from junior high to JV and is getting rocked. He needs something that will pad his upper ribs underneath his arms without impeding his ability to still play QB. If there aren't rib protectors like this, are there heavier duty shoulder pads that would protect him? I never dealt with rib problems when I played. I can only imagine the discomfort outside of the games. Any insight would be appreciated.
