Rod bearings/main bearings get intechanged all the time, but can mean the same thing.
Drop the pan, unblot the rods and look for scoring on the caps... if there is, I'd just pull the motor and rebuild.
The motor comes out super fast. You could get it out and broken down in one day and back together in another weekend.
