All in all, Blaine Gabbert said the week went well.

Gabbert, who sustained a shoulder injury last week, practiced full for a third consecutive day Friday, and was listed as probable on the Jaguars' injury report. The second-year quarterback is expected to start Sunday.

"It's something you have to manage and take care of," Gabbert said Friday as the Jaguars (1-5) prepared to play the Green Bay Packers (4-3) at Lambeau Field in Green Bay, Wis., Sunday at 1 p.m.

"Like I've said before and I'll say again, 'No one in this locker room is 100 percent from the first day of two-a-days.' . . . I feel like I had a great week."

Asked if he was "full go," Gabbert smiled.

"Yeah, I'm a rocket ship now," he said.

Jaguars Head Coach Mike Mularkey said Gabbert looked good throughout the week.

"I thought he threw the ball very well," Mularkey said Friday. "We had one ball on the ground today. Obviously, he didn't take any hits, but I don't see anything that makes me think he can't play."

Said Gabbert, "We had a great week of practice this week. You try to take a step forward in practice so you can take a step forward in the game, so from that standpoint we definitely improved. Now, we have to continue that with the game on Sunday and see how it works out."

As expected, the Jaguars also on Friday officially ruled running back Maurice Jones-Drew out for the Green Bay game. The three-time Pro Bowl selection sustained a sprained foot against Oakland last week.

Safety Dwight Lowery (ankle) also was ruled out, with running back Montell Owens (shoulder) listed as doubtful and cornerbacks Derek Cox (back) and Rashean Mathis (groin) listed as questionable.  Wide receiver Laurent Robinson (concussion) and fullback Greg Jones (hip) were also listed as questionable.

Cox worked limited throughout the week, with Mathis working limited the last two days after not participating on Wednesday. That makes the Jaguars' starting cornerbacks' status uncertain entering a game against Green Bay quarterback Aaron Rodgers, the 2011 NFL Most Valuable Player.

After signing cornerback Kevin Rutland on Friday, the Jaguars have four healthy cornerbacks in Will Middleton, Mike Harris, Aaron Ross and Rutland.

"Obviously, it's a concern based on the situation we're in with them being a five-receiver offense," Mularkey said. "We still have time to make those decisions of who's going to start and be able to play for us."

Mularkey said the injury situation played a role in Thursday's decision to place veteran linebacker Daryl Smith on injured reserve.

Smith, the Jaguars' all-time leading tackler, was placed on the league's new IR/designated to return list, which enables him to potentially return for the final two games of the regular season. Smith had been out since early in training camp with a groin injury.

"It just was not getting better," Mularkey said. "We wanted to give him some time, and he felt like it wasn't progressing. This was the best option for him. He still has a chance to play this year, and this gives us a chance to make some moves and get some guys up."

Mularkey said Smith wanted to have a chance to play this season.

"He appreciated that that was the option," Mularkey said.

Roster management also will play a role in the decision on when to elevate John Chick to the active roster, Mularkey said.

Chick, a defensive end who had 2.5 sacks last season, has been on the Physically Unable to Perform list all season with a knee injury. Mularkey said he is healthy enough to be activated for Sunday, but a move will depend on other roster considerations.

"We'd like to get him up," Mularkey said. "This is probably the most decisions we've had to make for a game. He'd be ready."

Mularkey called the time and effort Chick has put into returning this season "amazing."

"He's been in here every day," Mularkey said. "His wife was expecting, and I told him to go home three days before, to get some time. He was devastated that I wouldn't let him be in the building. He called me, 'Can I come back?' And it wasn't about having six kids. He literally felt like, 'I have to be there. I'm not going to get better being here. I have to be there.'''

Also on Friday, Mularkey said Keith Toston will be active and play special teams. The Jaguars re-signed the veteran running back in the wake of Jones-Drew's injury this week.

Mularkey also said Robinson, who has missed the last two games with a concussion, likely will be a game-time decision.
