GREEN BAY, Wis. – The Green Bay Packers might be without the one cornerback who had some measure of success in coverage Monday against Falcons star Julio Jones.

Davon House replaced the struggling Sam Shields in the fourth quarter and came up with a pair of pass breakups against the Atlanta Falcons' star receiver during his 11-catch, 259-yard performance.

But it was on one of those breakups – a pass that House almost intercepted in the end zone on a second-and-6 play from the Packers’ 12-yard line with 7:19 remaining – when he got hurt. Jones' knee caught House on the back of his right shoulder. House was slow to get up after the play but remained in the game.

House did not practice Wednesday, and coach Mike McCarthy said he did not expect him to practice Thursday, either, leaving his status in doubt for Sunday's game against the Buffalo Bills. House said he was scheduled to undergo more tests.

"It's really all up in the air right now," House said Wednesday. "We'll see what happens when we get these tests back and go from there."

House has had shoulder problems in the past. He was on his way to winning a starting job in 2012 until he separated his left shoulder in a preseason game at San Diego and missed the first six games of the season.

House has been in and out of the lineup this season in various defensive packages.

"It's never good when you're hurt, especially when you get a chance to play and you do all right," House said.

Shields, who went into Monday's game questionable because of a concussion, was not listed on this week's injury report.

Here's the Packers full injury report:

• CB Davon House (shoulder, did not practice)

• RB Eddie Lacy (hip, limited participation)

• G T.J. Lang (ankle, limited participation)

• LB Jamari Lattimore (ankle, did not practice)

• OLB Nick Perry (shoulder, full participation)

• G Josh Sitton (toe, limited participation)
