"That's been great," said Tollefson. "I've been able to learn not by watching, but by doing it. I make a few mistakes here and there, but I'm not making the same mistake twice. I'm learning."
At the beginning of training camp, Tollefson was a longshot to make the team. Now he suddenly has a chance, or at least be signed to the team's eight-man practice squad.
"Dave's done a real nice job," said McCarthy.
McCarthy did not give a specific date of Peterson's return, but it may be sometime next week prior to Green Bay's final preseason game at home against the Tennessee Titans on Sept. 1.
"He's questionable for this week (against Cincinnati) and the preseason is going to come to a quick close next week, so we're hopeful to get Kenny out there," said McCarthy.
If Tollefson can show that he's a valuable commodity for special teams, his chances of making the squad will improve even more, which he fully realizes.
"That's huge, that's huge, that's huge," Tollefson said. "That's one of the first things I did when I got here is talk to Coach (Mike) Stock and let him know that I'd be willing to do anything on special teams for him.
Tollefson missed a few practices and Green Bay's second preseason game against Atlanta last week with a pulled muscle in the area of his ribs. He returned to practices earlier this week, playing behind Kabeer Gbaja-Biamila.
"I just want to show them that I understand the defense and my responsibilities, and beyond that I'm going to give them 110 percent every play," Tollefson said. "Whether it's a pass or run, or whatever, I'm going to be in there and try to help the team out."
Punter gets tryout
The Packers gave left-footed punter John Torp, recently waived by the Minnesota Vikings, a workout Friday at Ray Nitschke Field.
Packers general manager Ted Thompson downplayed the tryout, saying, "We bring guys in every day for different positions."
The Packers have had a handful of punters in for tryouts during training camp, Thompson estimated.
The Packers released B.J. Sander earlier this week and, at least temporarily, have awarded the punting job to Jon Ryan.
The following players did not practice Friday because of injuries: offensive tackle Josh Bourke (calf), defensive lineman Kenny Peterson (ankle), tight end Tory Humphrey (elbow), running back Ben Brown (tailbone), offensive lineman Will Whitticker (hamstring), safety Atari Bigby (hand), cornerback Will Blackmon (foot), offensive lineman Mookie Moore (unknown).
McCarthy said that Whitticker's injury is worse than what was originally thought. The lineman has been out since the first week of training camp.
"He's frustrated," McCarthy said.
? Najeh Davenport returned to practice on Friday after missing the previous two days with a hip injury.
? While Davenport returned, running back Ahman Green left practice early with leg cramps.
? Rookie Abdul Hodge had the hit of the day during a ‘thud' tackling session when he de-cleated Noah Herron in the backfield. ‘Thud' means that the players cannot wrap up to make a tackle and bring the ball carrier to the ground. Hodge simply hit Herron, but went tumbling on his back.
"It's good you know any time you get a stop for the defense, it's a stop for the team, especially goal line," Hodge said, "and considering the team we're playing this week, they'll look to pound it."
"It could have been worse if it was in a game. I kind of went easy on him," Herron said. "The play earlier was a cut, but next time I'll take him."
? The Packers practiced inside the Don Hutson Center Friday because of the threat of rain but the rain didn't come, so the team invited its disappointed fans waiting to watch the team outside inside for about a half hour, which may have been a first. Practices inside the Hutson Center are usually closed to the public because of space limitations along the sidelines of the field.
