The Packers got an easy win on Monday night. But it didn’t come without a dark cloud.

Receiver Christian Watson left with a knee injury. More will be learned on Tuesday as to its severity.

“There’s some concern there, certainly,” coach Matt LaFleur said after the game, via Rob Demovsky of ESPN.com. “We’re going to get some more testing done tomorrow. Hopefully, I’ll have an answer for you tomorrow.”

Watson suffered the injury, returned to the game, and then exited for good.

“It definitely hurt right away, but it felt like it was good enough to go back in, so I went back in and it was feeling all right,” Watson said. “But it was just kind of lingering a little bit and I just couldn’t play the type of football I wanted to play, so I just had to shut it down.”

The Packers have clinched a playoff berth, and they could still finish as the No. 5 seed in the NFC. Whether five or six, they’ll be on the road to face the eventual champions of the NFC South or NFC West — and the Packers likely will be favored in either game.

The Packers face the Vikings on Sunday, in a game that was moved from 1:00 p.m. ET to 4:25 p.m. ET.
