Bill Horn, Harris' agent, said an MRI Monday revealed Harris had sprained his knee Sunday in a loss to the Dallas Cowboys, the Tribune reported.
"We'll find out more about him [Tuesday]," Horn said, according to the newspaper. "He told me he was 'cool.'"
Harris was one of several Bears defenders injured in the 34-10 loss to Dallas on Sunday night. Linebacker Lance Briggs
and cornerback Nathan Vasher left Sunday's game against the Cowboys with groin injuries, while an
ankle injury knocked offensive lineman Ruben Brown.
