John Harbaugh said Monday that it's clear the lingering injuries to Lee Evans and Domonique Foxworth are affecting their ability to make plays, and the Ravens are going to have to make a decision about whether or not it would be better to shut them down until they are healthy rather than continue to send them out there. Evans has been nursing a sore ankle for nearly a month, and it has limited his practice time. In the Ravens' 26-13 loss to the Titans, he looked like he was having trouble finishig his routes, and he was unable to come back to the ball on a play where quarterback Joe Flacco threw an interception. "I think it's affecting him," Harbaugh said of Evans. "There is no doubt about it. We're going to have to take a hard look at that. To me, if he can do the things we need him to do, he plays. If he can't, he won't play. We've been nursing this thing now for a month. And I don't see it getting a lot better. So either he can play like we need him to, or he can't. The same thing goes for Domonique Foxworth." Foxworth, who had surgery to repair a torn anterior cruciate ligament less than a year ago, was beaten several times by wide receivers during the Ravens' first two games. Although the Ravens didn't plan on him having him start this year, injuries to Jimmy Smith and Chris Carr have forced the Ravens to use him in a more prominant role. "I don't think he feels like it's a 100 percent," Harbaugh said of Foxworth. "He's said that before. And it's definitely showing up in the way he's playing. He's playing very, very conservatively. And he knows -- we all know -- we've just got to get that thing right if that's what it is." Harbaugh made it clear he wasn't trying to single out Evans and Foxworth for their poor play. But he feels it's clear it's reached a point where the Ravens can't keep sending them out there, asking them make plays even though they're not 100 percent. "If they can't play the kind of football we need them to play because they're injured, it's no fault of theirs," Harbaugh said. "These guys are gutting it out. But they'll have to sit for awhile until they're healthy and then we'll see how that goes this week." The Ravens are also going to be without wide receiver David Reed for at least three weeks, Harbaugh guessed, after he injured his shoulder against the Titans. "It's probably three weeks, but I'm not a doctor, even if I play one during press conferences," Harbaugh said. "That's what it normally is."
