Green Bay Packers star quarterback Aaron Rodgers will not face the Dallas Cowboys this weekend, according to ESPN.
Rodgers will remain sidelined with a fractured left collarbone, an injury sustained against the Chicago Bears on November 4.
He has been a limited practice participant this week, but Green Bay Packers (6-6-1) coach Mike McCarthy ruled his starting quarterback out on Friday afternoon.
"He's very disappointed," said McCarthy. "He's frustrated. Speaking with [doctors], it's the right decision."
The decision means back-up Matt Flynn will start for the Packers again this week. The former-Oakland Raiders quarterback led the Packers to a narrow victory over the Atlanta Falcons at Lambeau Field last Sunday.
The Packers beat Matt Ryan's team 21-22 last weekend, and Flynn will lead his side again as they travel to Texas to take on the Cowboys.
The game could have crucial playoff implications for both teams, as both are on the cusp of a postseason push.
With three games remaining in the regular season, the Packers sit in third position in the NFC North behind the Bears (7-6) and the Detroit Lions (7-6).
But they only trail by half a game, and could easily overhaul both the Bears and the Lions with a strong finish to the campaign.
Their chances would have been boosted significantly by the return of Rodgers, one of the best quarterbacks in the NFL, but they will have to continue in his absence for at least another week and hope to remain in the hunt.
