McCown will undergo surgery Tuesday to address a torn hamstring, Tim McManus of ESPN.com reports.
EDGE Analysis
The 40-year-old suffered and played through the torn hamstring during Sunday's wild-card loss to the Seahawks, which makes his solid performance in place of Carson Wentz all the more impressive. McCown ended a two-month retirement to join the Eagles in August, and there's a decent chance he'll retire again given the eventful and painful finish to the season.
