Ask any Chicago Bears fan how many sacks their team has registered so far in 2015, and most of them wouldn't even miss a beat: Zero. New defensive coordinator Vic Fangio instilled his 3-4 base defense upon his arrival to Chicago, but without much talent to work with, the Bears have struggled to generate any sort of semblance of a pass rush.
According to Ian Rapoport, the Bears are flying in former San Diego Chargers defensive lineman Mitch Unrein to sign him to a contract.
Former #Chargers DL Mitch Unrein has already found work. Source said he's flying to Chicago to sign with the #Bears. Will help immediately

Unrein spent five season with the Denver Broncos, with four of them being under John Fox. He was signed this year by the Chargers, but released when they had to make room for tight end Kyle Miller.
Unrein has good size (6'4, 306 pounds), and will likely be worked into the Bears defensive rotation pretty quickly.
We'll have more updates as they are available.
EDIT: The Bears officially announced the Unrein signing and to make room, they released Lavar Edwards.
