The reoccurrence of an undisclosed illness that already has forced cornerback Samari Rolle to miss four games this season will sideline the Baltimore Ravens' standout 10-year veteran again this week.
Baltimore officials already have ruled Rolle out of Sunday's home game against Cincinnati and there remains no definitive timetable for his return.
Asked if there is a possibility Rolle might not play again in 2007, Ravens head coach Brian Billick told the Baltimore Sun: "I don't know that. That's really not for me to answer. That's for the doctors to see if they can get this thing under control."
The Ravens and Rolle have steadfastly declined to discuss the illness in any detail and, after Monday night's loss in Pittsburgh, a game in which Rolle did not play, teammates and club officials avoided all attempts to discuss the illness. While the condition is not believed to be life-threatening, it did hospitalize Rolle for a brief period earlier in the season.
Also earlier in the year, the Ravens said Rolle would miss playing time because of a reaction to the medication he was taking for the condition.
"I'm off," Rolle said at the time. "I can't play. As far as being straight and balanced and coordinated, I'm not."
Rolle, 31, has played in four games in 2007, and has 13 tackles, one interception and two passes defensed. For his career, Rolle, who made the Pro Bowl in 2000, has appeared in 136 games and has 470 tackles, 28 interceptions and 110 passes defensed.
Prior to this season, Rolle, who entered the league as a second round pick of the Tennessee Titans in 1998, has missed only 12 games.
Baltimore does hope to have its other starting cornerback, Chris McAlister, back this week after he also missed Monday night's game.
