"I knew it was two-minute offense, so less runs," Bolton said. "Just trusting what I do every day in practice, drop to where I needed to be. (Brown) made a great play on the ball, popped it up in the air. I went up and got it."

With Burks on the mend, Bolton is currently competing with the likes of seventh-round pick Ty Summers, second-year linebacker James Crawford and practice-squad holdover Brady Sheldon for the spot next to Martinez.

After practicing with the starting defense this past week, Bolton said he leaned on Martinez for tips about the defense, and knowing when to take a risk at the right time.

Bolton was around the football all night. He forced Ravens starting quarterback Lamar Jackson into a third-down incompletion off a blitz to end the Ravens' opening series and made two solo coverage tackles to stymie kickoff returns.

There still were areas Bolton wants to improve, though. He's trying to strike the right balance between aggressiveness and passiveness when it comes to filling gaps and tackling.

Green Bay is still gathering data about how long it will be without Burks, a third-round pick out of Vanderbilt a year ago, but Martinez said he felt comfortable with the two series he played with Bolton.

"It felt good," Martinez said. "It's kind of a work-in-progress thing, watch the film and see what we can correct, get those little mistakes out of there. But yeah, it's been good so far and he's hungry to learn and get better."

A one-year starter at Oklahoma who suffered a nasty ankle injury a year earlier as a junior, Bolton hasn't forgotten the attention the Packers showed him in an otherwise quiet pre-draft process.

If the Packers call upon him to start again next week against the Oakland Raiders in Winnipeg, Bolton will be ready.
