I do not believe that would be possible. If there was some restriction then there would be loss of power to where the vehicle would eventually just stop running if the restriction was really bad. For the main bearing to have spun you would need lack of lubrication. More manufactures are starting to blame aftermarket oil filters for this. Here is a service bulleting from KIA

Aftermarket Oil Filters & Engine Noise Complaints
During engine research & development, the mechanical engine lubrication system is designed to operate at specific volumes and pressures to keep the reciprocating & rotary components properly lubricated. Kia has assigned specific guidelines for the use of oil filters (Cartridge / Spin-on) and oil viscosity to conform to; filtration, leak down, oil flow rate and pressure variations, to keep the lubrication system at optimal performance.
The use of aftermarket oil filters/ o-rings / improper oil viscosities could result in less then optimal filtration, leak down, oil flow rate and pressure variations due to different oil filter designs and construction. Some of the symptoms and concerns that may arise with aftermarket filters / wrong oil viscosities include:
- Valve train Noise
- Engine Knocking Noise
- Cold Start Engine Noise (2-7 seconds duration)
- Idle / Cruise Engine Noise
- Whistle Noises
Kia recommends the use of Kia genuine parts that are designed to operate at the specifications set forth during engine lubrication design and testing. If the engine oil has been changed recently and a noise condition has developed, perform an inspection of the oil filter and or Customer oil change maintenance records to help you in determining if an aftermarket filter or the wrong oil viscosity was used. If the vehicle is equipped with an aftermarket oil filter, perform an oil change and filter with the correct oil grade / viscosity and a replacement genuine Kia oil filter at the customer's expense.
This is not a warranty repair and any related damage is not warrantable, nor is changing the engine oil and filter to isolate this condition.
So what you should try as a first step is drain and catch some of the oil and inspect for shiny flakes in the oil. Remove the oil filter and inspect as well. Install an OE oil filter and correct viscosity oil and recheck. If the noise is still present and the filter is contaminated with a lot of shavings, then a tear down of the lower end should be done for further evaluation?
