Access Vikings morning walkthrough: Zimmer coaches with a heavy heart, Vikings' ball boy extraordinaire, more

On most mornings, we walk you through what's going on with the Vikings.

WHAT YOU MIGHT HAVE MISSED

— Coach Mike Zimmer's father passed away Tuesday night. After yesterday's practice, Zimmer choked up as he called his dad "a heck of a mentor."

— Offensive coordinator Norv Turner confirmed that running back Adrian Peterson is OK, but he admitted "we all held our breath for a second."

— Meet Terrell Barnes, the Vikings' equipment assistant and ball boy extraordinaire who buzzes all over the practice fields here in Mankato.

— The Captain Munnerlyn situation has been a little curious, but the veteran cornerback said he isn't worried about job security. Speaking of the Captain, Munnerlyn practiced with an edge yesterday.

— About half of the team's passes Sunday night went to tight ends and running backs. Turner said you can expect more of that this season.

— Packers rookie QB Brett Hundley knows he won't see the field in the regular season, so he hopes to make the most of his preseason action.

— The Lions retooled their offensive line in the offseason. And because it's that time of year, of course the Lions think that group can be great.

— The new regime in Chicago has no ties to former first-rounder Shea McClellin, so he is going to have to earn a starting spot at linebacker.

TODAY'S VIKINGS SCHEDULE

The Vikings have changed their schedule for the final day of training camp. They practice from 9-10:30 a.m. and the walkthrough is at 3 p.m. After that, the team will spend the night packing for the move back to Winter Park.
