The Jaguars' much-maligned WR corps underwent yet another change as Troy Williamson was lost for the season with a torn labrum and Nate Hughes was waived.

Hughes dropped two balls in the endzone in Sunday's 31-17 loss to the Cardinals. His release was a bit surprising considering Williamson's injury and prompted coach Jack Del Rio to comment that the NFL is "a tough business."

Without Williamson and Hughes, rookie WRs Mike Thomas and Jarett Dillard are likely to be in action in Week Three after being inactive the first two weeks. They're expected to be slotted as the Nos. 3 and 4 receivers behind Torry Holt and Mike Sims-Walker, who had a 100-yard outing vs. the Cardinals.

Another rookie pass catcher, TE Zach Miller, is also primed for action after sitting out the first weeks recovering from a broken kneecap. The club released No. 2 TE Greg Estandia in anticipation of Miller's return.
