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.

The most optimistic time frame for Romo after the second broken collarbone of his career 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.
