Hawk was back on the field for the first time since suffering a strained muscle in his chest in the first preseason game Aug. 11.
Head coach Mike McCarthy suggested after practice that the only thing or person standing in the way of Hawk's making it all the way back for game action in Week 1 is the discretion of team doctor Pat McKenzie.
"I thought he looked good just from watching him on the field today," McCarthy said. "He looked like his normal self. He was flying around at practice, and he is a very physical player, so it was good to have him back out there."
McCarthy said range of motion doesn't appear to be an issue anymore for Hawk, who was shut down from contact work for the final three weeks of the preseason.
"We knew that A.J. was going to rehab at a rapid pace, and in his mind, he feels he has been ready for quite some time," McCarthy said. "So, it is a combination of the individual, and it is a combination of the doctor's report.
"As far the movement and so forth, I think he is really past all of those stages, whether it's pushing, reaching, pulling. It's just a matter of Pat McKenzie — clearing him to play."
The Packers will know more about Hawk at the end of their lengthy week of preparations for the game. They had practices Monday and Tuesday, were off Wednesday and finish with three straight practice days until Saturday.
Having Hawk available on Monday would be of benefit to the Packers defense, which was maligned by injuries throughout the preseason and has the unenviable task out of the gate to try to keep Vikings running back Adrian Peterson from busting loose.
The Green Bay run defense was exploited in the exhibition games without Hawk manning the weak-side linebacker spot and with massive tackle Ryan Pickett sidelined with a hamstring injury the entire preseason.
Pickett began practicing Monday and said he will be OK to start the game, though he admittedly won't be in football shape for several weeks.
"I think Adrian Peterson is an exceptional running back, just the way he blasted onto the scene last year, and having the opportunity to be around him at the Pro Bowl," said McCarthy, who was head coach of the NFC team in the February all-star game. "He's an impressive young man. But, run defense is what it is, as they say. It's gap control, attitude, the ability to separate and tackle. He's definitely someone that has the ability to bounce the football and make you pay when you're not in your proper gaps."
If the medical staff deems that Hawk would be better off for the long haul of the season by not suiting up Monday, Brandon Chillar would be pressed into the starting assignment. The Packers signed Chillar, formerly of St. Louis, as a free agent in the offseason.
