Rolle has been out for the past four games and underwent neck surgery. He is hopeful that he might be able to play this week if doctors clear him for contact.
Rolle met with doctors Monday.
"We think he’s got a good chance to come back," Harbaugh said. "Samari is a heck of a corner. When we get Samari back, we’re going to be that much stronger in the back end."
Rolle was initially forecast to be out four to five weeks, but is ahead of schedule.
"We talked about Samari having neck surgery, and I guess that conjures up images of traction in all of our minds," Harbaugh said. "There’s a bone graft involved, and I guess they say Samari has got really strong bones and he’s coming back quickly."
Landry, who suffered a spinal cord concussion, is scheduled to be examined today.
Harbaugh has cited Landry’s upper body strength and musculature as positive factors in his recovery.
"I was a little surprised in both those cases that you could come back that quickly in these situations," Harbaugh said.
Meanwhile, offensive tackle Adam Terry is scheduled to undergo arthroscopic surgery today on his sprained right knee. Terry also has a lateral meniscus issue, and he could be back in two or three weeks depending on what doctors find when they perform the procedure.
"It’s a little bit of an opportunity to go in there and just see what the deal is," Harbaugh said. "He’s got a slight meniscus tear on the outside, and that’s something you can play with.
"We’ve been trying to get that thing back and see if he could play with it, but it’s not coming back as quick as we had hoped. So, they’ll go in there and see if they have to sew it back up or clean it up or whatever they do to it, and we think he’ll be back in two or three weeks with the surgery."
With Terry sidelined, Willie Anderson will continue to start at right tackle with Chris Chester lining up inside at right guard.
A converted tight end,
"Chris Chester came in and did a nice job," Harbaugh said. "He was physical. He was up to the standard of that group, a little bit with his style of play.
"I think he’s got a lot to be proud of. The fact that we didn’t have miscommunications back there, no real busts, that’s a big credit to the whole group."
SMITH MOVING UP: Former Heisman Trophy winner Troy Smith recovered well enough from his tonsil infection to overtake Todd Bouman as the backup quarterback.
"I think his strength is back," Harbaugh said. "He looks like he’s just about to where he was before, if not 100 percent. He’s progressing as a quarterback, too.
"He’s getting closer to what we saw there in training camp where he was that third preseason game. He figures into our plans as we go forward."
A MATTER OF INTENT: Following his unsportsmanlike conduct penalty for allegedly taunting Dolphins return specialist Ted Ginn, linebacker Antwan Barnes insisted that he was just leaning over to help up rookie safety Haruki Nakamura.
The officials saw it differently as they interpreted that he was taunting Ginn after Nakamura’s tackle.
"We take Antwan at his word," Harbaugh said. "I think that’s what he was trying to do, and so it’s unfortunate. He’s going to have to be careful with his body language as we go forward."
REVIEWABLE: Harbaugh said he will request that the league review a borderline hit by Dolphins Brandon London where he blindsided tight end Edgar Jones on a kickoff return in front of an official. Although the shot transpired after Jones was forced out of bounds, there was no flag.
"We will be sending that one in along with our usual plays," Harbaugh said. "It will be interesting to see what they say."
PLAYING HURT: Running back Willis McGahee turned in a gutty performance against the Miami Dolphins, rushing for 105 yards and a touchdown after having a lot of fluid drained from his left knee prior to kickoff.
