The Jacksonville Jaguars released an injury report on Monday night -- despite the fact that the Jaguars only participated in a walkthrough for Monday's practice -- as the Jags gets ready to take on the Indianapolis Colts in Week 10, on Thursday Night Football.

Greg Jones, Maurice Jones-Drew, Rashean Mathis and Dwight Lowery would not have participated in practice had the Jaguars held practice on Monday. Jaguars head coach Mike Mularkey already ruled Jones-Drew out for Thursday's game against the Colts, and it's still unknown when the injured running back will return to the playing field.

Mathis has missed the last two weeks with a groin injury, and the early signs point toward Mathis sitting out Thursday night's contest.

Montell Owens, Brad Meester and Derek Cox would have been limited in practice. With Mathis still hurting, the Jaguars will need Cox to be healthy come Thursday.

Though injury reports typically come later in the week, the Jaguars and Colts are forced to release injury reports on Monday, in advance of their game, since it is scheduled for Thursday night.
