Giordano was just waived by the Packers two weeks ago. If he makes the final roster, he'll be limited to special teams duty.

After years of getting burned in St. Louis, Hill was limited to eight games with the Falcons last season. Despite the team's desperation at cornerback, Hill was relegated to bench warming late in the season. The former first-rounder won't draw much interest on the open market.

The Falcons are looking to upgrade their depth at wide receiver this season, so the Auburn product will be replaced on the roster by a better player.

Grimes showed improvement as a starter down the stretch, but the addition of Dunta Robinson will push him into a more appropriate battle for nickelback duties in 2010.

Zelenka, 34, signed off the street late last season and snapped in five games for the Falcons. He'd spent his previous eight years with Jacksonville.

The deal should be finalized on Monday. Atlanta is expected to receive Detroit's sixth-round pick and switch places with the Lions in round five. Houston, the No. 41 overall selection in 2007, is immensely talented but fell out of favor last season despite starting more games than any Falcons cornerback. He is a press corner, which would fit well in Lions defensive coordinator Gunther Cunningham's man-to-man secondary.

Williams is going on age 31 and tore his ACL in October, but is a longtime pal of coach Mike Smith and wasn't an obvious liability before his injury. Still, he should have a hard time winning back a starting job, assuming the team upgrades its corner situation as planned. Another option would be moving Williams into a third safety/nickel back role if he's able to play at 100%.
