The Dallas Cowboys suffered a catastrophic injury last week, when quarterback Dak Prescott’s left hamstring gave out on him against the Atlanta Falcons. Midway through the third quarter, Dallas lost their franchise signal caller, an injury that’s expected to leave an already lackluster passing game worse off.

Prescott had been averaging 241 passing yards a game and had a career-worst 3.8% touchdown rate, against a 2.8% interception rate. After signing a $240 million contract extension in the offseason, Prescott and the Cowboys have floundered on offense this season.
