Head Coach Mike McCarthy says Rodgers is working with the rehab group Wednesday.
Rodgers was carted to the locker room in the second quarter of Sunday night's opener against the Chicago Bears with a left knee injury, but he returned after halftime to lead a 20-point comeback victory, despite putting little weight on his left leg.
Rodgers said after the game he would undergo more tests, though he planned to play against Minnesota.
The Packers are slated to host the Vikings at 1 p.m. ET Sunday. Quarterback Kirk Cousins displayed both his particular skill set and toughness in the win, and wide-out Adam Thielen provided several big plays to continue Viking drives and set up scores.More news: Alibaba’s co-founder Jack Ma to retire next week, say reports
"Haven't even thought about that", Rodgers said when asked if he had confidence in Kizer if the backup needed to start.
"There was a lot of adrenaline", Rodgers told reporters, "and (it's) pretty sore the last three days".
If the soreness keeps Rodgers out of practice for the rest of the week, that doesn't necessarily mean he won't play against the Vikings. He echoed McCarthy by saying it's one day at a time. "He'll be given the whole week to get ready. We'll take it day by day and learn as we go".
One person who's convinced Rodgers is going to play is Mike Zimmer. "So, we'll see what tomorrow brings".
