San Diego Chargers linebacker Melvin Ingram left Friday's 12-10 preseason win over the Minnesota Vikings with a left knee injury.

Ingram was helped off the field by trainers after injuring the knee rushing the passer in the third quarter.

He was the 18th overall pick in the 2012 NFL Draft out of South Carolina. He had 10 sacks for the Gamecocks in 2011.
