Heap still has not practiced since suffering a hamstring injury two weeks ago against the Steelers, but head coach John Harbaugh said yesterday that he's optimistic that his two-time Pro Bowl tight end will be able to play this Sunday against the Saints.
"I'm hoping. I'm hoping he'll be back," Harbaugh said. "We'll just have to see. Hamstring (injuries), you just never know about. He's making good progress. We'll just have to see."
Mason (ankle) and Zbikowski (back) also sat out again today, as did fullback Le'Ron McClain, who was sent home by trainers because of an illness.
For the Saints, running back Chris Ivory (hamstring) was downgraded to no practice today.
Three other starters are down as having a full practice - safety Malcolm Jenkins (rib), cornerback Tracy Porter (shoulder) and tight end Jeremy Shockey (groin). Jenkins and Shockey were both upgraded after having a limited practice yesterday.
