GREEN BAY, Wis. (AP) — This hasn’t been an ideal start to a busy week for the Green Bay Packers.

They lost 28-22 to the Minnesota Vikings on Sunday in a game that revealed how they need to shore up their run defense and get more production from wide receivers other than Davante Adams. Then they had a player test positive for COVID-19 for the first time this season.

All this comes as Green Bay (5-2) prepares to visit the San Francisco 49ers (4-4) on Thursday in a rematch of the NFC championship game that the Packers lost 37-20 last season. Packers coach Matt LaFleur said Monday he’s preparing for the game to go on as scheduled even after the positive test.

“It’s the situation that we’re presented with, and we’re going to make the best of it,” LaFleur said. “It’s not an excuse to go out there and play bad or anything like that. It is what it is, man. You’ve got to adapt and adjust.”

This short week wouldn’t have given the Packers much time to get ready for the 49ers game even without the positive COVID-19 test.

The Packers haven’t announced who tested positive, but they did place rookie running back A.J. Dillon on the COVID-19 reserve list Monday. That list is for players who either test positive for COVID-19 or who have been in close contact with an infected person.

The Packers lost to the Vikings by allowing Dalvin Cook to rush for 163 yards, catch two passes for 63 more yards and score four touchdowns.
