ENGLEWOOD, Colo. --Offensive lineman Donald Stephenson, tight end Virgil Green and outside linebacker DeMarcus Ware remained sidelined as the Broncos began their preparations for Sunday's game at Tampa Bay.

Ware's absence was expected; he is projected to miss another three to four weeks following forearm surgery on Sep. 20 after being injured two days earlier against the Indianapolis Colts.

But Green and Stephenson are considered "day to day" after not traveling to last Sunday's game at Cincinnati because of calf injuries they suffered in the Week 2 win over the Colts. Neither practiced last week before being ruled out for the Bengals game.

Safety Shiloh Keo was also sidelined, but was at practice. Keo was held out because his knee swelled up Tuesday, Kubiak said.

"We weren't doing a whole lot today -- a lot of teaching today -- so we'll rest him today," Head Coach Gary Kubiak said. "My expectations are for him to be back [Thursday]."

All other Broncos were on the practice field, including left tackle Russell Okung, safety T.J. Ward and inside linebacker Brandon Marshall, all of whom were treated on the field during the Bengals game. Okung missed part of the second quarter with a lower-back injury, while Ward had a stinger; both returned to the game. Marshall left late in the contest after becoming fatigued; he played more snaps than any other Broncos linebacker in the win.
