The Raiders are believed to have plenty of depth this year. It could end up being tested.

Defensive lineman Mario Edwards Jr., a second-round pick in 2015, left Friday night’s game in Arizona with a leg injury. Edwards was carted to the locker room.

As a rookie, Edwards appeared in 14 games with 10 starts. He suffered a season-ending neck injury in Week 15.

Before leaving the playing area via cart, Edwards walked off the field with assistance.
