Saints' Terron Armstead: Set to miss 3-to-4 weeks

Armstead was diagnosed with a pectoral injury Wednesday and is expected to be sidelined for 3-to-4 weeks, Ian Rapoport of NFL Network reports.

Armstead, the Saints' starting left tackle, sustained what was initially labeled a shoulder injury during the Week 10 win over the Bengals. Follow-up examinations revealed the nature and extent of Armstead's setback, which will prompt the Saints to lean on veteran Jermon Bushrod to protect Drew Brees' blind side for multiple games. Armstead previously hadn't missed a snap all season before his early departure against Cincinnati.
