The Chargers have placed tackle Jared Gaither on the “Reserve-Injured” list with a groin injury.

Gaither played in four of the team’s 10 games. He missed almost all of training camp and the first three games of the regular season with a back injury. He suffered a groin injury late in the Chargers’ Oct. 7 game against the Saints.

Danario Alexander was on the field for snaps last week instead of a healthy Robert Meachem, but Malcom Floyd technically took over Meachem's position.

Floyd played the "Z" receiver, which was previously played by Meachem and Vincent Jackson in the past.

The “Z” typically lines up on the same side as tight end Antonio Gates.

The Tampa Bay Buccaneers improved to 5-4 with a 34-24 win over the San Diego Chargers.

The Buccaneers had a +1.5 advantage in The Trench Counter, forcing two turnovers that were returned for touchdowns and matching the Chargers on a yards per play basis. San Diego had a +19 edge in Total Rushes/Completions.

Josh Freeman went 14-for-20 for 210 yards and two touchdowns.

Doug Martin had 119 total yards from scrimmage one week after his monster performance against the Raiders.

Philip Rivers went 29-for37 for 337 yards and three touchdowns, but also threw two interceptions.

Ryan Mathews continued his relatively disappointing third season, rushing 17 times for just 54 yards.

Ryan Mathews has the ability to break long runs, but hasn't done so since being a first round pick by the San Diego Chargers in 2010.

Mathews has carried the ball 475 times in his career, but none have gone for 40 or more yards. Only BenJarvus Green-Ellis and Shonn Greene have 300 or more carries since 2010 without a 40-yard gain.

The focus is to polish Mathews' decisions and habits in the open field through film analysis and game experience.

“I've got to score when I get plays like that,” said Mathews, who had a season-long gain of 31 yards last week against the Chiefs. “Regardless of where I'm at on the field, if I get a breakaway, I've got to score with it. It's all it is.”

The San Diego Chargers ended a three-game losing streak by defeating the reeling Kansas City Chiefs 31-13.

The Chargers had a +13.0 advantage in The Trench Counter, gaining 7.2 yards per play compared to 4.8 for the Chiefs, along with a +2 edge in turnover differential. Kansas City, however, had a +5 edge in Total Rushes/Completions.

Philip Rivers went 18-for-20 for 220 yards, two touchdowns and one interception.

Ryan Mathews rushed 13 times for 67 yards without a fumble.

The Chargers pulled away early in the fourth quarter with a Malcom Floyd touchdown, followed by a Shaun Phillips fumble recovery for a touchdown and a Demorrio Williams 59-yard pick-six.

Matt Cassel went 19-for-29 for 181 yards, an interception and a fumble.

The Chargers limited Jamaal Charles to just 39 yards on 12 carries.

Philip Rivers has struggled this season, but he had a strong performance throwing downfield in the San Diego Chargers' 31-13 win over the Chiefs on Thursday.

Rivers was 8-for-8 for 135 yards and two touchdowns on throws 10 yards or greater downfield.
