Being shot while wearing a bulletproof vest

[lotus0kid]

Hello! I have a character who was shot at close range in the chest while wearing a bulletproof vest. I know when that happens, he'd have some severe bruising- how likely is it that he'd crack/break a rib as well? The bullet hit right over his heart, I would hope those ribs are pretty tough, but if a rib is damaged, would he be able to feel/see where the fracture was through his skin after it has healed (this character is definitely on the scrawny side)?

I've Googled "healing cracked ribs," "injuries after being shot while wearing a bulletproof vest," and "rib anatomy."
