Vikings quarterback Kirk Cousins rolled out to his left and launched the football downfield on the play, finding Thielen in the end zone.
Thielen reeled in the 25-yard pass and successfully kept both feet in bounds while making the grab.
The star wide receiver’s momentum, however, carried him into a wall separating photographers and fans from the field. Thielen slid and appeared to have hit his feet on the wall.
He came off the field in obvious pain and didn’t return, with the team later revealing he’d suffered a hamstring injury.
Thielen is set to undergo an MRI on Monday to see the extent of the injury. A source told Pro Football Talk the team fears his status is week-to-week. Thielen told reporters after the game he was optimistic about playing Thursday night against the Washington Redskins, according to the Pioneer Press.
“We’ll evaluate it, see where it’s at after getting an MRI, and then hopefully I’ll get ready to go,” he said. “I’m optimistic that I’ll be playing, and that’s all we can do right now.”
The touchdown grab was Thielen’s only catch in the game.
The Vikings won, 42-30, and improved their record to 5-2.
