Chargers' Melvin Gordon scores two touchdowns in first half

— -- KANSAS CITY, Mo. -- Held without a touchdown in his rookie year, San Diego Chargers running back Melvin Gordon did not take long to rectify that in his second season.

Gordon scored on a 1-yard plunge to cap San Diego's opening drive of the game against the Kansas City Chiefs, and he got in from 6 yards out on the next series. The Wisconsin product finished with 39 rushing yards in the first half, helping the Chargers grab a 21-3 lead at halftime.

He finished the game with 57 yards on 14 carries and the two touchdowns in the Chargers' 33-27 overtime loss to the Chiefs.

Gordon totaled just 641 rushing yards in his rookie season with four fumbles lost. He finished last season on injured reserve with two games left after tearing cartilage in his left knee, which required microfracture surgery in January.

Gordon worked with mentor Minnesota Vikings running back Adrian Peterson during the summer in Houston to get ready for his sophomore campaign and said before the season that he felt more comfortable and confident in San Diego's offense.
