The Pro Bowl cornerback was on the practice field Monday afternoon, when the team reconvened after its bye week.

Harris is eyeing a return to action when the 4-3 Packers, who have won two straight games and are tied for first in the NFC North, play at the Tennessee Titans on Sunday.

"It's been tough (being out)," Harris said. "I'm glad we're back on the winning side of the record part of it, but it's been tough."

Harris has missed the last four games after suffering a lacerated spleen in the Packers' 27-16 loss to the Dallas Cowboys on Sept. 21.

The injury was initially thought to be serious enough that it would end Harris' season and possibly his career.

The prognosis took a turn for the better, though, after Harris underwent a series of tests and sought multiple opinions from doctors about whether he could safety return to the field this season.

Harris was cleared to do individual drills away from practice before the bye week.

Packers head coach Mike McCarthy said the team's medical staff is taking a cautious approach with Harris this week, classifying it as a "trial return," and won't rush him back into a game.

"It's important to get Al back on the practice field, just to see where he is, and get him back to football shape, and there's no substitute for that," McCarthy said. "Every player goes through it. You can condition with the best of them, and you still have to get out there and tug and pull and do the things that are required to get you in football shape."

Harris is expected to be eased into team drills Wednesday.

As for the possibility of having Harris reclaim his starting spot Sunday, McCarthy said, "We'll answer that question at the end of the week. It's an option, though. Hey, it would be great to have Al out there starting, but I'm only going to put him out there when he's ready."
