Practice report: Shields still sidelined

GREEN BAY, Wis. -- The hamstring injury that took out cornerback Sam Shields at the last minute before Sunday’s game against the New York Giants remains problematic.

The Green Bay Packers’ best cover man was not on the field when the team returned to practice on Wednesday to begin preparations for Sunday’s game against the Minnesota Vikings at Lambeau Field.

Shields was listed as probable for last week’s game despite not practicing on Friday. However, he was declared inactive after a game-day workout did not go well.

“Sam didn’t feel it was serious but obviously as time approached the game, it was not where he needed to be,” Packers coach Mike McCarthy said earlier in the week.

The Packers also were without another top cornerback, Casey Hayward, who is expected to miss multiple weeks with a recurrence of the hamstring injury he first sustained before training camp.

Others who did not practice on Wednesday were: quarterback Aaron Rodgers (collarbone), cornerback James Nixon (knee), linebacker Nick Perry (foot), tackle Don Barclay (knee) and defensive tackle Johnny Jolly (groin).

The full injury report will be available after practice.

Rookie offensive lineman JC Tretter practiced on Wednesday for the first time since he broke his ankle during an offseason practice on May 20. Tretter, a fourth-round pick from Cornell, can practice for up to three weeks before the Packers must decide whether to activate him. Two other players on the physically unable to perform list, safety Sean Richardson (neck) and defensive end Jerel Worthy (knee), began practicing last week.
