Reports on the radio and elsewhere suggest that Brown's injury was suffered in practice yesterday (Wednesday).
The oft-criticized defensive end has been somewhat more effective in the second-half of the season. Foge Fazio has moved Brown to the right to the left side for passing downs, which has met with some success. Brown, however, continues to be regarded as a disappointment given his draft position.
There are no details available as of yet regarding the injury. We will bring them to you when they become available.
