Two divisional foes with excellent defenses will meet on Monday Night Football, when the Arizona Cardinals host the San Francisco 49ers tonight at 8:30pm EST on ESPN. Arizona got off to an excellent start at 4-0, but Ken Whisenhunt’s club has since dropped three in a row and needs a win at home. San Francisco stands at 5-2 and atop the NFC West, having won three of its last four games.

Two divisional foes coming off drastically different  Week 6 contests will meet on Thursday Night Football, when the San Francisco 49ers host the Seattle Seahawks at 8:20 p.m. EST on the NFL Network. The 49ers were surprisingly “out-physicaled” against the Giants last week, losing the NFC Championship Game rematch 26-3 at home.

NFC West rivals will clash tonight when the St. Louis Rams host the Arizona Cardinals at 8:20 pm EST on the NFL Network. The Cardinals have been one of the better stories in the NFL after one month, as Ken Whisenhunt’s club is one of only three undefeated teams in the league. Arizona has won 10 of the last 11 meetings against the Rams, but St. Louis has won both of its home games under new coach Jeff Fisher.
