Colts' Jerrell Freeman concussed

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.
