IRVING, Texas — Dallas Cowboys quarterback Tony Romo is expected to miss about two months with a broken left collarbone, though he won't need surgery.
The loss of Romo in Sunday's 20-10 victory at Philadelphia means the defending NFC East champion Cowboys (2-0) will be without their starting quarterback and All-Pro receiver Dez Bryant possibly through October.
Coach Jason Garrett said Monday that tests revealed no ligament damage for Romo after the second broken collarbone of his career. The other was in 2010, and he missed the final 10 games of the season. However, Dallas was out of playoff contention before he could have returned.
The most optimistic time frame for Romo's return is during a two-game Florida swing on Nov. 15 (Tampa Bay) and Nov. 22 (Miami). Otherwise, his absence could approach three months if he skips a short week for the Thanksgiving home game against Carolina and returns Dec. 7 at Washington.
Dallas hosts Atlanta (2-0) on Sunday.
Brandon Weeden replaced Romo against the Eagles and threw a clinching 42-yard touchdown pass to Terrance Williams in the fourth quarter.
Weeden started in place of Romo once last season after the Dallas started sustained a back injury, losing to Arizona. It was Weeden's eighth straight loss as a starter going back to his two-year stint with Cleveland after the Browns drafted him late in the first round in 2012.
