Ravens tight end Todd Heap will be a game-time decision for Sunday's game against the Cleveland Browns.
Heap, who has missed the past two games with a pulled right hamstring, has practiced on a limited basis for three straight days and is listed as questionable. He told coach John Harbaugh he felt "very good."
"I think we'll wait until game time just to see for sure," Harbaugh said after Friday's practice, "and see how it feels up there with the weather [in Cleveland]."
Heap acknowledged Friday that there have been "ups and downs" during practices this week.
"We're at the point of the season where you have a couple of goals, and one of them is right in front of us," Heap said. "I've got to be smart how we go about it. We'll see what happens."
Heap said his status remains day-to-day.
"I'm going to test it out on Sunday and just be smart," he said.
David Reed out
Harbaugh held out hope that David Reed could play Sunday despite a concussion, but the Ravens ruled out the rookie kick returner and wide receiver.
Reed had not practiced all week because he had yet to pass post-concussion tests. Earlier on Friday, Harbaugh said the team would continue testing Reed up until Sunday, but Reed was ruled out in the organization's final injury report of the week.
Jalen Parmele is expected to be the team's primary kick returner, but he said his objective isn't to replicate what Reed, who leads the NFL with a 29.3-yard average on kick returns, has done.
"My biggest thing is no negative plays, which means 100 percent security, 100 percent catches and making positive yards," Parmele said. "That's my biggest focus, to not put our offense in bad situations. I can't really worry about averages. I've just got to be smart back there."
Zbikowski not on IR
Safety Tom Zbikowski is dealing with a bulging disc in his back, but he hasn't been ruled out for the season.
Zbikowski hasn't practiced for the past two weeks and was ruled out for Sunday's contest. The Ravens finish the regular season at home against Cincinnati on Jan. 2.
"It's something that we think he has a chance to play with," Harbaugh said. "He doesn't have anything radiating into his legs. That's a very good sign. There might be a little bit of a ligament strain in there that we've treated with some cortisone this week. We think we have a chance to get him back. We just have to see how it responds to that."
Other injury news
Cornerback Chris Carr, who did not practice Friday because of an illness, is considered questionable. Defensive end Cory Redding (elbow) also did not participate, but he is probable.
Wide receiver Derrick Mason (ankle), linebacker Brendon Ayanbadejo (knee) and safety Haruki Nakamura (illness) were upgraded to full participation and are listed as probable.
Center Matt Birk (knee), wide receiver Marcus Smith (shoulder), offensive lineman Tony Moll (illness) and linebacker Jason Phillips (illness) practiced fully and are probable.
Harbaugh: 'It's our turn'
Harbaugh didn't devote too much time Thursday night to watching the Pittsburgh Steelers' 27-3 rout of the Carolina Panthers.
"I watched a little bit of it," he said. "Then, I checked in on the score. And then I lost interest pretty quickly."
The Steelers' victory means the Ravens must win at Cleveland to stay in contention for the AFC North title and the No. 2 seed in the AFC.
"That was good for them," Harbaugh said. "They got it done. Congratulations to them. We just move forward. Now, it's our turn. We have to step up."
Ed Reed fined $10,000
Ravens safety Ed Reed was fined $10,000 for his roughing-the-passer penalty on the New Orleans Saints' Drew Brees on Sunday.
The NFL disciplined Reed because "he unnecessarily struck the quarterback in the head and neck area with his forearm," a league spokesman said.
The spokesman said there was no fine for Saints defensive end Will Smith, who appeared to knee the Ravens' Joe Flacco in the head after the quarterback was sacked. Flacco yelled at officials after the play because they didn't throw a flag.
