Cowboys HC Mike McCarthy: 'Dak is our quarterback'

Earlier this week, Jones said that Prescott could make an earlier-than-expected return from his thumb injury — possibly as early as Week 4. In place of the two-time Pro Bowler for the tail end of Week 1 and all of Week 2 has been Rush, who helped lead Dallas to its first win last Sunday.

Rush finished the Week 2 victory over the Cincinnati Bengals 19-for-31 with 235 passing yards, one touchdown and no interceptions, along with a 95.5 passer rating. The 28-year-old led the team on a six-play drive in the final minute of the fourth quarter to set up Brett Maher's game-winning 50-yard field goal as time expired.
