Thomas (knee) participated in spring practices and appears ready for the start of training camp, Vic Tafur of The Athletic reports.
The third overall pick from the 2017 Draft had a disappointing end to his tenure with the 49ers, tearing the ACL, lateral meniscus and medial patellofemoral ligament in his left knee in Week 2 last season. Thomas then signed a one-year, $3.25 million contract with the Raiders in March, and an aggressive rehab program got him back on the practice field just seven months after the initial injury. He won't necessarily be a starter in Las Vegas, but he'll at least have the opportunity to earn snaps off the bench at both defensive end and defensive tackle.
