Nate Sudfield will be sidelined for six weeks after undergoing surgery to repair a broken bone above his left wrist, according to a source.
Sudfield suffered the injury during Thursday night's preseason game between the Philadelphia Eagles and Tennessee Titans.
He was expected to serve as the No. 2 quarterback behind Carson Wentz this season with Nick Foles gone.
The Eagles also have Cody Kessler and rookie Clayton Thorson on the roster.
