Khalil Mack missed the first two days of the Raiders offseason workout program, and it’s uncertain when he’ll join teammates in Alameda.

The elite edge rusher is looking for a new contract, and it’s possible he’ll keep his distance until a pact has been reached.

The Raiders would prefer their best defensive player were participating in voluntary offseason workouts, but they aren’t stressed about it.

"This is going to be a big contract and all sides are trying to make everything work," McKenzie told’s Steve Wyche on Wednesday. "It's about the end result. One thing I know is that we love Khalil Mack and we want to make him a Raider for life. We'll get through all the other stuff. We understand the business part of it. Everybody is aware of everything and nobody is surprised. Everything, on all sides has been positive. I can't stress that enough."

McKenzie says these talks aren’t contentious. Both player and team are committed to working out a long-term deal that could set the market for defensive players. That could lead to a deal exceeding Von Miller’s $114 million contract that included $70 million guaranteed.

McKenzie understands Mack might not report until a deal gets done.

Wyche also reported that Mack has spoken with new head coach Jon Gruden, and that relationship is positive despite Mack’s absence.
