Green Bay wide receiver Greg Jennings returned to practice on Tuesday, giving the Packers a boost ahead of their visit to Seattle for Monday Night Football this week. However, both he and the team suffered a setback on Thursday.

Jennings didn't train today and coach Mike McCarthy, speaking on SiriusXM Radio, said: "He worked the other day (Tuesday) and it didn't go as well as we thought. It's been up and down. I know he’s frustrated and he doesn’t feel like he has a handle on it yet."

Jennings didn't play in last week's manhandling of division rival Chicago, having picked up a groin injury during the fourth quarter of the Week 1 defeat to San Francisco. Clearly, he wasn't missed against the Bears, but Aaron Rodgers would like to have his No. 1 receiver available for a difficult trip to the Pacific Northwest against an opportunistic Seahawks secondary.

Seattle will fancy their chances against the Packers regardless of whether Jennings plays or not. Green Bay, however, will fancy their chances a lot more with him in the lineup.

Jennings caught five passes for 34 yards in Week 1, numbers that would ideally need to be improved upon on Monday night.
