Jacksonville Jaguars linebacker Daryl Smith has officially been ruled out for Sunday's game against the Minnesota Vikings. Smith has been dealing with a groin injury he suffered early in training camp and has yet to play a snap in the preseason and will now miss the first regular season game. The Jaguars have gotten solid play out of backup linebacker Russell Allen, who has been playing for Clint Session, but will now need to fill Smith's spot on Sunday.

According to the team, linebacker Kyle Bosworth will get the start at the position, as he's been filling in for Smith on the first team during the preseason. The Jaguars have decent enough depth at the linebacker position when everyone is healthy, but now it's running thin with both Session and Smith out of the lineup.

Smith is a big loss for the Jaguars defense, as he's their best cover linebacker and a three-down player. I would expect the Vikings offense to target the Jaguars linebackers on Sunday, as they're down to just one starter in Paul Posluszny.
