Brian Schottenheimer secured his first NFL preseason win as the head coach of the Dallas Cowboys, defeating the Atlanta Falcons 31-13 on Saturday. Now, the Cowboys are starting to prepare for the regular season opener, trimming their roster down to 53 players.

FRISCO, Texas -- As the Dallas Cowboys look to get down to the 53-man roster limit, veteran offensive lineman La'el Collins is among the players who have been released. Collins joined the Cowboys during training camp after injuries on their offensive line to Tyler Guyton (knee), Rob Jones (neck) and Saahdiq Charles (knee).

The Cowboys are looking to bounce back from a disappointing 7-10 season that went off the rails long before quarterback Dak Prescott was lost to injury midseason. New head coach Brian Schottenheimer gets his first crack at commanding an entire team after spending the last three seasons as the offensive coordinator for Mike McCarthy.
