The Cowboys play the Philadelphia Eagles next Sunday night for the NFC East Division title and a playoff spot. Dallas has no made the playoffs in the past three seasons.
“I tweaked it in the game,” Romo said about his back, per the Cowboys’ official website. “For whatever reason, just the twist or whatever that was, definitely just made it not feel comfortable.”
Romo’s backup is veteran Kyle Orton, who has only attempted five passes this season for 40 yards. Romo was having a good season completing 64 percent of his passes for 3,828 yards with 31 touchdowns and 10 interceptions.
