Green Bay Packers wide receiver Christian Watson appeared to suffer a hamstring injury during the fourth quarter of Sunday night’s matchup against the Kansas City Chiefs.

Watson was running off a jet sweep when he got a first down and looked as if he was deciding on whether to stay in bounds or run out. He ended up taking a knee and likely tweaked his hamstring in the process, though we can’t be sure he didn’t feel something right before opting to go down.

He was helped off the field and into the medical tent.

Watson had a big night for Green Bay, registering 71 yards and two touchdowns, as well as two carries for 15 yards.

The Packers hung on for a 27-19 win following some key contributions from their pass-catchers.
