Pitts is feared to have suffered an MCL tear in his right knee during Sunday's 27-24 win over the Bears and could require surgery, Ian Rapoport of NFL Network reports.
Rapoport relayed that the MRI that Pitts underwent Monday revealed more substantial damage than initially anticipated. Pitts reportedly is seeking a second opinion, but he looks like he could be in danger of missing the rest of the season. Falcons head coach Arthur Smith may provide an official update on Pitts' health during his media availability later Monday.
