According to TMZ:
Denver Broncos backup QB Chad Kelly was arrested in Colorado early Tuesday morning after cops say he broke into a home around 1 AM.
The Englewood Police Dept. says officers were called to the home at 1:17 AM in reference to a man standing outside the residence. While cops were en route, the man entered the home.
According to court records, Kelly sat down on a couch next to the home owner ... as she held her baby. The woman said Kelly was "mumbling incoherently."
Cops say a male inside the house hit Kelly in the upper back with a 2-3 foot stick shaped piece from a vacuum ... and was able to chase him outside.
Officers searched the area and were able to locate Kelly inside of a black SUV.
