Baltimore Ravens linebacker Ray Lewis likely will miss the next two games with a toe injury, according to multiple league sources.
The sources also said Lewis has informed team officials that he hopes to return to the field after Week 12.
Lewis, who is listed as questionable on the team's injury report, missed all three practices this week, and it was reported that the All-Pro linebacker flew to South Florida this week to visit a foot specialist.
"The thing about Ray, is Ray is Ray," Harbaugh said. "You can't count Ray out. ... Ray may not go, he may go. The Bengals will have to prepare for him either way."
Harbaugh added: "It's something he could possibly play with. (It's) not any kind of a serious, serious thing."
Wideout Lee Evans (ankle) also was listed questionable Friday after practicing on a limited basis all week. Evans has not played since Week 2.
