The better question might be how Rodgers' strained left calf might limit him in Sunday's NFC divisional playoff game at Lambeau Field.
"I'm going on Sunday," Rodgers said Wednesday. "It's just a matter of how."
McCarthy held Rodgers out of practice on Wednesday, meaning he has not been on the field since he reinjured his left calf in the Dec. 28 regular-season finale against the Detroit Lions. The Packers practiced twice last week during their playoff bye, and Rodgers missed both. They have two more practices this week -- Thursday and Saturday.
"I plan on Aaron playing Sunday," McCarthy said after Wednesday's practice. "Today's schedule was for him to stay exclusively in the training room. There's still some things that he needs to work through. We'll see what tomorrow brings, if he'll be able to practice. It's day-to-day, but everything points in the direction of him playing."
Rodgers met Wednesday morning with team physician Pat McKenzie, who determined Rodgers wasn't ready to practice.
"It just kind of depends on how it feels," Rodgers said. "I met with Doc. I've seen him every day. Nothing really changed on the schedule. This was kind of the plan from the start. It's progressing, but we'll see how it feels tomorrow."
Rodgers' mobility was limited significantly when he returned after missing two series against the Lions. He did not leave the pocket on any of his second-half passing attempts, although he completed 11 of 13 passes and a touchdown. He also scored on a 1-yard quarterback sneak.
When asked whether he will be able to do everything he normally can, Rodgers said: "We'll see."
"It's Wednesday," he added. "So hopefully it keeps progressing."
