Cowboys vs. Lions: Dallas Makes 4 Roster Moves, Adds New RB

The Cowboys have elevated tight end Sean McKeon and running back Malik Davis from practice

 squad ahead of Sunday’s game vs. the Lions. Additionally, Carlos Watkins has been signed to the 53-man roster to help along the

 D-line. And made official was the shift of rookie tackle Matt Waletzko to injured reserve.

The Watkins move suggests that Dallas might not activate rehabbing D-lineman Tarell Basham just yet,

and the McKeon move looks like insurance as Dalton Schultz works through a knee issue.

Also, the Davis elevation is to replace injured third-stringer Rico Dowdle.

OCT 21 ROOKIE OUT Matt Waletzko, the 6-8 rookie offensive tackle with the recurring shoulder issue,

as the eventual surgery will be performed now, per the Dallas Morning News.

The bad news arrived here at The Star on an otherwise happy day with the full return of Dak Prescott

 to practice as the first-teamer and the planned starter in Week 7 vs. Detroit.

Waletzko, the Cowboys' fifth-round draft pick, first suffered the injury to his left shoulder during his senior year at North Dakota.

 He played through it in college but it popped up again as a problem in training camp,

and Dallas entered the process knowing that the 22-year-old, who has worked as a swing tackle in his first season here, would eventually need surgery ... and that time is now.
