According to Jim Wexell via his twitter account the Steelers 6th round draft choice Ra'Shon "Sonny" Harris will be signed by the Steelers today. Harris is currently on the Carolina Panthers practice squad but is eligible to sign to another teams active roster at any point. In order to make room for Harris either Aaron Smith will be placed on the Injured Reserve list or the Steelers will be forced to cut another player. Any guesses on who loses a roster spot? UPDATE: According to Adam Schefter Sonny Harris has been signed and the Steelers have placed Aaron Smith on Injured Reserve.
