Prescott's strained hamstring is likely to sideline him for an extended period, Dallas owner Jerry Jones said. The Cowboys also are trading for receiver Jonathan Mingo, according to a source.

The Cowboys finally saw a positive injury development Wednesday, as Micah Parsons returned to practice for the first time since suffering a high ankle sprain in a Week 4 win over the Giants. The three-time All-Pro defensive end participated on a limited basis Wednesday and said he feels confident he can be fully healthy for Sunday’s game against the Eagles.

The Dallas Cowboys defense hasn't been the same without three-time All-Pro edge rusher Micah Parsons. That's obvious even without looking at the numbers.  However, Parsons could very well return in Week 10 against the 6-2 Philadelphia Eagles after not playing since the second half of Week 4 at the New York Giants because of a high ankle sprain.
