IRVING, Texas — Dallas Cowboys quarterback Tony Romo is expected to miss about two months with a broken left collarbone.
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 wide 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.
The most optimistic time frame for Romo to return is during a two-game swing in Florida on Nov. 15 (Tampa Bay) and Nov. 22 (Miami).
Brandon Weeden replaced Romo against the Eagles and threw a clinching 42-yard touchdown pass to Terrance Williams in the fourth quarter.
Dallas hosts Atlanta (2-0) on Sunday.
