Brock Hoffman got first-team reps at left guard for Smith. Before Mazi Smith left with an injury, Solomon Thomas and Osa Odighizuwa got work on the first-team. The Cowboys are mixing and matching the cornerbacks and Kemon Hall got work on the second team as the nickelback. Hall got a pass breakup in practice.

If healthy, Collins can help solidify a Cowboys offensive line that was recently hit with an injury to starting left tackle Tyler Guyton. Cowboys coach Brian Schottheimer recently tabbed Asim Richards and Nate Thomas as two players "who'll get the first couple cracks" to temporarily replace Guyton, who is slated to miss the next 4-6 weeks.
