Uhh ... we're pretty sure fingers aren't supposed to bend like that.
Arizona Cardinals wide receiver Rondale Moore's pinky is pretty busted right now ... and if you needed proof, just check the cringeworthy update he posted to his Instagram page on Wednesday.
It's unclear how it happened -- Moore was placed on Injured Reserve last month with a groin injury ... but regardless of how it happened, it appears he visited a doctor in Beverly Hills to get it fixed.
Unclear whether the digit is broken or dislocated .
