Cowboys' Dak Prescott to start throwing; Cooper Rush expected to start play Why the Cowboys are the Eagles' toughest test so far (0:55) Domonique Foxworth discusses what Jalen Hurts' performance vs. the Cowboys on Sunday night will reveal to fans going forward. (0:55) 12:34 PM ET Todd ArcherESPN Staff Writer Close Covered NFL since 1997, Cowboys since 2003 Previously covered Bengals and Dolphins Lives in Dallas area with his wife and two children FRISCO, Texas -- Dallas Cowboys quarterback Dak Prescott will throw passes Wednesday for the first time since undergoing surgery on his right thumb, but he is expected to miss his fifth straight game Sunday against the Philadelphia Eagles . "We are preparing for Cooper [Rush] to start against the Eagles," coach Mike McCarthy said Wednesday. McCarthy said Prescott will throw to receivers after Wednesday's practice. He will go through the quarterback school (a pre-practice walkthrough just for the QBs) and go through some individual drills but not take part in any of the practice.

"I think we're still in the medical rehab phase," McCarthy said. "So once he clears this phase and he's fully activated, then I think that's when we have our conversation." Prescott had surgery on Sept. 12 -- a day after the Cowboys' season-opening loss to the Tampa Bay Buccaneers . While owner and general manager Jerry Jones said there was hope that Prescott could return within four weeks -- and did not put the quarterback on injured reserve -- that was always the most optimistic view. The timetable for a return was between four to six weeks after he had a plate inserted into stabilize the thumb. McCarthy repeated that he wants Prescott to get a full week of work before returning as the starter. He would not get into a potential thought of having Prescott serve as Rush's backup as he continues to mend. The Cowboys have won four straight games with Rush, but McCarthy does not believe the team's path with Prescott would have altered if the record would have been different. "You've got to trust the medical process," McCarthy said. "This is a 17-game season. That was my immediate response. I know Dak didn't want to hear it, but you got to make sure that he's right for the long haul, too. "So I'm not saying we're being conservative because that doesn't line up with him, with the way he approaches preparing to play. But, yeah, this really is following the medical timeline. He's doing all the things you can possibly do and more to get ready. But I don't think it would've changed, from my view."
