Every weekday, we walk you through what's going on with the Vikings.

WHAT YOU MIGHT HAVE MISSED

— Coach Mike Zimmer doesn't like what he's seen at the strong safety position through four games. Second-year defensive back Antone Exum could be the solution.

— Wide receiver Mike Wallace is confident he'll play Sunday, and receiver Charles Johnson and safety Andrew Sendejo were healthy enough to return to practice.

— Michael Rand explains why the Vikings better take advantage of the next five games.

— The Vikings don't expect Kansas City's offense to change much despite the loss of star running back Jamaal Charles.

BEHIND ENEMY LINES

— The Chiefs believe running back Charcandrick West is a poor man's Jamaal Charles. West is in line to replace the injured Charles for the rest of the season.

— Vikings star running back Adrian Peterson provides hope for Chiefs' injured star.

— Kansas City's secondary has struggled to defend this season.

TODAY'S VIKINGS SCHEDULE

Coordinators George Edwards, Mike Priefer and Norv Turner are set to be on the podium at 11 a.m. Then the Vikings practice at 1 p.m.

SOMETHING TO THINK ABOUT

Brock Vereen hasn't been with the Vikings long, but the practice squad safety could be the young talent the team needs to solidify that position. He has 19 games of NFL experience and had four years of success playing at TCF Bank Stadium with the Gophers. The Vikings have had success with young talent filling in over the past few weeks. Maybe the Gophers product would do the same. However, the coaches aren't convinced yet. "It's still a learning process for [Vereen]," Zimmer said. "I would say at this point, Anthony Harris has a better chance of getting in the mix than Brock Vereen does."
