METAIRIE, La. Starting cornerback Tracy Porter and first-team defensive lineman Shaun Rogers both sat out practice Thursday as the Saints continued preparation for Sunday's home-opener against the Bears.
Porter (right calf) had tightness in his calf during the morning and was in pain walking, Saints coach Sean Payton said.
'I think it's something that came in practice and it wasn't real significant initially,' Payton said of Porter's injury.
Rogers was excused for a family matter.
Additionally, defensive tackle Tom Johnson, who has been limited in practice with a left calf strain that he originally injured in the preseason opener, did not practice.
'There's enough in training camp and enough that we've seen that we think he's closer than further away in regards to getting back on the field,' Payton said. 'It's one of those injuries that if you hurry it back, you can be set back with it so you have to be cautious.'
Kicker Garrett Hartley (right hip) and receiver Marques Colston (right collarbone) also were out.
Strong safety Roman Harper (right ankle) and receiver Lance Moore (groin) were limited, good signs for both. Harper did not participate Wednesday while Moore continue to work towards a return after missing the past three weeks since originally straining his groin in Oxnard, Calif.
For Chicago, four players did not participate in Thursday's session: safety Chris Harris (hamstring), guard Lance Louis (ankle), receiver Roy Williams (groin) and running back Marion Barber (calf), who was limited a day earlier.
Cornerback Zackary Bowman (hamstring) and linebacker Lance Briggs (knee), who both were limited on Wednesday, were full participation on Thursday.
And linebacker Brian Urlacher returned to practice after tending to family issues earlier in the week.
