Robinson, a seventh-year pro from North Carolina State, was officially reinstated by NFL Commissioner Roger Goodell on Oct. 18 and was practicing under a league roster exemption since Oct. 22. The exemption expired at 3 p.m. (CT) today.
Robinson warmed up prior to Green Bay's Monday night game against Denver, but coach Mike McCarthy decided not to activate him for the game.
"I just didn't think that Koren was ready," McCarthy said. "He needs another week of work. He had some inflammation in his knee. He had the surgery done a number of months ago. It surprised him a little bit. He wasn't comfortable out there. He kind of went through his first week of training camp. We'll visit it tomorrow and make some decisions there."
Robinson played in four games with the Packers last season as a kick returner and reserve receiver. He caught seven passes for 89 yards (12.7 avg.) He was leading the team with 12 kickoff returns for 253 yards (21.1 avg.) when he was placed on the reserve/suspended by commissioner list by Goodell on Oct. 17.
Wynn started four games at running back for the Packers this season and saw action in all seven games. He rushed for 203 yards and four touchdowns on 50 carries, but was hampered by nagging injuries that either kept him out of parts of games and/or practices.
Wynn sustained nerve damage in his shoulder after his only carry of the night against the Broncos. The rookie, who suffered neck spasms as a result of a hit in practice last week, plunged into a pile of blockers and tacklers from the Packers' own end zone and injured his shoulder.
"Injuries are an unfortunate part of the game," McCarthy said. "I think you look at DeShawn Wynn, and I'm very pleased for what he's accomplished in the short time he's been here. He's a seventh-round pick. He had to fight like hell at the end of training camp the last week. He missed training camp with a significant injury (quadriceps), and heck, he was our starting running back at one point. I think he has a very bright future. It's unfortunate that he has to go down on IR, but we're excited about DeShawn's future here. Because he has all the ability. He can be as good as he wants to be."
McCarthy said today that Wynn's injury is "signifcant" and similar to offensive lineman Tony Moll's neck stinger injury that caused him to be out for more than a month between training camp and the start of the regular season.
With Wynn on the shelf, the Packers will turn to Ryan Grant, who rushed for a career-high 104 yards on 22 carries in Green Bay's 19-13 overtime win over the Broncos.
"I thought Ryan Grant made very good decisions," McCarthy said. "I thought his course work was very good. There's a couple things we need to clean up in his draw footwork and things like that, but he hasn't had a lot of opportunities to rep that in practice. But I thought our fits up front were the best they've been all year, and I thought it was a good run-game performance. Very happy with the way Ryan took advantage of his opportunity, and he will be in the No. 1 slot when we go to Kansas City."
