The Indianapolis Colts have signed 23-year old saftey Al Afalava.  Afalava played in 13 games as a rookie for the Bears last season and he had 53 tackles, 7 passes defensed, 2 sacks and 1 forced fumble.  With the state of the Colts’ D right now I wouldn’t be surprised to see Afalava working a lot on defense as early as this weekend.  25-year old safety Chip Vaughn has been placed on the Injured Reserve List with a ankle injury ending his season.  Vaughn played in 3 games for the Colts last season and he had 1 tackle.
