Dak Prescott and the Dallas Cowboys entered Sunday's matchup against the Atlanta Falcons with a chance to get their season back on track. A win could have improved their record to a respectable 4-4 mark. Not exactly great, but good enough to give them an outside chance at competing for a playoff spot.

Yet, after falling to 3-5 instead, now there's more uncertainty about Mike McCarthy's job security. Jerry Jones recently addressed those concerns after Sunday's loss, but now the team has an even bigger issue relating to their franchise quarterback.

According to NFL Network's Ian Rapoport, Prescott's injury is "much worse" than everyone initially believed. Now the Cowboys quarterback is expected to miss "multiple weeks."

Prescott is seeking a second opinion to verify what the Cowboys' doctors have found. For now, the team is avoiding placing the NFL's highest-paid quarterback on injured reserve, but it's possible that move will come over the next few days.

Cooper Rush will take over as the Cowboys' starting quarterback. Yet, if he doesn't play well, it's possible we'll see former third overall pick Trey Lance take over in the future too. The Cowboys' next three matchups are against the Eagles, Texans, and Commanders.
