The concerns about Raiders defensive end/linebacker Khalil Mack should be alleviated.

“I’m feeling like a million bucks,” Mack said Thursday. “I’m ready to go.”

Mack sat out practice Wednesday with a hamstring injury and was seen hobbling toward the end of Sunday’s win over the New York Jets. But he said he’ll return to practice Thursday and isn’t concerned about the hamstring.

“I’m out there today full force,” Mack said.

As theorized, Wednesday was just about giving an important player who isn’t quite 100 percent some rest and there should be no fear that Mack won’t play on Sunday in Pittsburgh.
