According to Bears reporter Jeff Dickerson, Head Coach John Fox stated linebacker Pernell McPhee underwent arthroscopic right knee surgery, still no timetable for return. Fox also said it was more of a "clean up" procedure. (Jeff Dickerson via Twitter)
McPhee has been sidelined since middle of 2016 season due to knee injuries. His future outlook does not look great as he can't seem to fight off these injuries. Take caution or look elsewhere if drafting in IDP leagues.
