The Cowboys are on their fourth starting quarterback of the season.
Kellen Moore will start on Sunday at Buffalo, coach Jason Garrett confirmed on 105.3 The Fan this morning. Moore replaced Matt Cassel, who was benched against the Jets, on Saturday night.
Saturday night’s game was the first regular-season appearance of Moore’s career. He spent three seasons with the Lions but never got on the field, then joined the Cowboys this year.
Dallas opened the season with Tony Romo as its starter, but he suffered a broken collarbone and was replaced by Brandon Weeden. The Cowboys then traded for Cassel and benched Weeden for him before Romo returned only to break his collarbone again. The Cowboys have since released Weeden, who is now with Houston, and now they’ll turn to Moore.
