The Jaguars have placed 27-year old linebacker Freddie Keiaho on the Injured Reserve List ending his season due to a severe concussion.  Keiaho looked pretty good in the pre-season opener against the Eagles when he had 5 tackles.  He played in 16 games (2 starts) with the Colts last season and he had 38 tackles, 1 sack and 1 pass defensed.  This a blow to the linebacker depth on the Jaguars as they liked Keiaho.
