SAN DIEGO -- The Indianapolis Colts lost starting linebacker Jerrell Freeman to a concussion in the second half of their game against the San Diego Chargers on Monday.
Freeman went into Monday leading the Colts in tackles with 39. He had eight tackles in the first half against the Chargers.
Mario Harvey replaced Freeman in the lineup.
The loss of Freeman means the Colts were without two starters. Safety LaRon Landry has missed the past four games with a high-ankle sprain.
