Cooper (hamstring) doesn't have an injury designation for Sunday's game against the Falcons, Michael Gehlken of The Dallas Morning News reports.
Cooper was held to two catches for 37 yards in an ugly loss to Denver last week, but he's mostly been effective while playing through the hamstring injury, including an 8-122-1 receiving line against the Vikings in Week 8. He gets a friendly matchup with the Falcons this Sunday, though Atlanta does have A.J. Terrell playing at a high level at the left cornerback spot. Cooper moves all over the formation, with a little more than one-third of his snaps this season coming at the right perimeter spot where he'd line up directly across from Terrell.
