Suggs, a three-time Pro Bowl pick, will miss his first NFL game in seven years -- ending his streak at 105. He probably will be out up to three weeks.
Quinn was fined an undisclosed amount for the hit on Suggs during Monday night's game in Cleveland and has apologized.
Harbaugh says he was "disappointed" with Quinn's block and that "there was no reason" for it.
