Hopefully, T.J. Hockenson didn't suffer a major injury. There's plenty of reason for concern.
Except for the illegal block ( in the back ) penalty, I thought T.J. Hockenson played well. His effort made the difference in picking up a 1st Down on a 3rd Down play on the Lions final drive. Hockenson helped prevent an interception later on in the drive. His in-line blocking seemed noticeably better in recent games than earlier in the season.
