Anyone else see Mos Def in the New York Classroom?

At the beginning of the movie, I swear I saw Mos Def (extremely briefly) during Garfield's (Samuel L. Jackson) demonstration of centrifugal force with the bicycle. During the slow-motion camera work when Garfield began flipping through the book that had '187' written on every page, the camera cut around the room and showed three students, the last of which I'm pretty sure was Mos Def(It was 1/2 a second at the most). This had to be one of his first appearances on camera as he did not debut until he appeared in 'Where's Marlow (1998)'. This would be consistent as Mos Def is from New York and the school that the Garfield character taught science at was Roosevelt-Whitney High in New York City.
