Cowboys move Parker to the sideline as Love tests Dallas on Sunday night

Christian Parker will coach from the sideline at Lambeau Field on Sunday night, with Mike Pettine upstairs and Jordan Love's deep passing waiting on the other side. Dallas' defensive changes face an immediate test against Green Bay at 8:20 p.m. Eastern on NBC.

The Cowboys are 2-3 after a 24-16 home loss to Tampa Bay. Green Bay is 3-2, and its last meeting with Dallas finished in a 40-40 overtime tie. In two games against the Cowboys, including the playoffs, Love has thrown six touchdown passes without an interception.

ESPN's Sunday NFL Countdown breaks down the downfield throws Dallas needs to contain in the first segment:

Overshown remains unavailable

Brian Schottenheimer said Friday that Pettine reports directly to him and has been studying film as he catches up with Dallas' defense.

Dallas will be without DeMarvion Overshown, Cobie Durant and Drew Shelton, as expected. Joey Porter Jr. and Ameer Speed are not on the final inactive list after carrying questionable designations during the week.

Prescott has weapons to answer

Green Bay's safeties have their own difficult assignment. CeeDee Lamb and George Pickens entered the week with a combined 66 catches for 857 yards and five touchdowns. In the Packers' official preview, Xavier McKinney and Evan Williams discussed disguising coverages long enough to keep Prescott from identifying favorable one-on-one throws before the snap.

Prescott had been sacked only six times through five games. The Cowboys scored 102 points across three games before managing 16 against Tampa Bay, leaving Green Bay to prepare for an offense capable of much more than its last outing.

Green Bay cornerback Brandon Cisse is active after being questionable with a hip injury. Benjamin St-Juste remains out, and guard Aaron Banks is also inactive. Defensive tackle Anthony Campbell returns after missing three games with an ankle injury.
