AFC West Results: Chiefs Lose At Home; Chargers Make 2nd Half Comeback

Though they got off to a quick start in the first half, the Minnesota Vikings were unable to hold their 17-7 lead over the San Diego Chargers. Philip Rivers led the Chargers to 17 unanswered points in the second half of the game for the 24-17 victory. Running back Mike Tolbert was also key to the victory.

Tolbert, who caught a one-yard touchdown pass from Rivers in the first half, opened the second half with a seven-yard touchdown run to cap a seven-play, 69-yard drive. Punter Mike Scifres had to take over kicking duties since kicker Nate Kaeding went down with an injury on Percy Harvin's 103-yard kick return touchdown that kicked off that game, Scifres made this extra point and all the others, and he came up with a 40-yard field goal to tie the game at 17.

After the Chargers defense forced the Vikings into a three-and-out, Philip Rivers took the team down the field, aided by an unnecessary roughness penalty, and ended the drive with a 19-yard touchdown pass to Mike Tolbert, his third touchdown of the game.

While Rivers threw for 335 yards, the Vikings' Donovan McNabb was just 7-of-15 for 38 yards and a touchdown pass. His first pass as a Viking was an interception.

The Vikings (0-1) host the Tampa Bay Buccaneers (0-1) next week. The Chargers (1-0) fly across the country for a game against the New England Patriots.

Rivers and running back Mike Tolbert guided the offense to two touchdowns

The San Diego Chargers are in much the same position as the Kansas City Chiefs were earlier in the day. The Chargers are losing to the Minnesota Vikings, 17-7, at halftime.

Minnesota Vikings new quarterback Donovan McNabb threw his first pass for an interception, but he's settled down since then. He found Michael Jenkins for a three-yard touchdown late in the second quarter for the halftime 17-7 lead. However, McNabb has just 37 yards passing.

Of course, what really made this game exciting at kickoff was Percy Harvin's 103-yard return for a touchdown. The Chargers' lack of execution on special teams in 2010 has carried over to the 2011 squad, it seems. Kicker Ryan Longwell added a 33-yard field goal in between those scores.

San Diego quarterback Philip Rivers has relied on tight end Antonio Gates, completing five passes for 36 yards. However, running back Mike Tolbert came up with the one-yard touchdown reception from Rivers. The Vikings intercepted Rivers at the end of the first half. Rivers is 15-of-25 for 142 yards.

The Kansas City Chiefs are the first AFC West team to pick up a loss this season. They were completely outclassed by the Buffalo Bills in a 41-7 defeat on Sunday afternoon. Buffalo quarterback Ryan Fitzpatrick was the offensive star of the game, throwing four touchdown passes.

Fitzpatrick fired off back-to-back touchdown passes in the first quarter and threw two more in the third quarter. Rian Lindell added six points on two field goals in the second quarter. C.J. Spiller's nine-yard touchdown run was set up when Chiefs quarterback Matt Cassel threw an interception into the waiting hands of Brandon Flowers.

The Chiefs started the game on the wrong foot when the opening kickoff was lost by Dexter McCluster and then recovered by the Bills. They put their only points on the board when Matt Cassel found Jamaal Charles in the end zone for a six-yard touchdown pass.

The Chiefs (0-1) visit the Detroit Lions next week. The Bills (1-0) host the Oakland Raiders.

The Kansas City Chiefs might find themselves as the first team with a mark in the loss column if they are unable to overcome the Buffalo Bills' 41-7 lead. The Chiefs were losing, 20-7, at halftime and have been unable to find any offense. Playing mostly out of a no huddle offense during their first two possessions of the second half, the Chiefs picked up a first down on Matt Cassel's first pass, but failed to move the chains on that drive and in the next one.

Buffalo quarterback Ryan Fitzpatrick added two more touchdown passes and now has four for the game. He found Scott Chandler on an 11-yard pass, the tight end's second touchdown of the game, with less than five minutes left in the quarter. Then with about three minutes left in the quarter, Fitzpatrick led another drive down the field that resulted in four-yard touchdown pass to Donald Jones.

Cassel followed that Bills touchdown play by throwing an interception. On the ensuing Buffalo drive, C.J. Spiller found his way into the end zone on a nine-yard run.

The Kansas City Chiefs are currently the only AFC West team in action and they are losing to the Buffalo Bills at Arrowhead Stadium, 20-7. The Bills wasted no time in the game when they recovered a fumble by kick returner Dexter McCluster. Kelvin Sheppard returned the ball to Buffalo's 26-yard line. After a couple of Fred Jackson runs, the team was inside the 10-yard line, eventually scoring on a Ryan Fitzpatrick four-yard pass to tight end Scott Chandler.

Fitzpatrick found Steve Johnson in the end zone for a 27-yard touchdown before the final minute of the quarter. Rian Lindell added field goals of 29- and 38-yards to increase the lead to 20-0 in the second quarter.

After the two-minute mark, Kansas City running back Jamaal Charles caught a six-yard touchdown pass from Matt Cassel. The Chiefs entered halftime with points on the board. Cassel has thrown 87 yards on 11-of-17 passing, but is averaging just 5.1 yards per attempt.
