BaltimoreRavens.com is reporting that Suggs suffered the injury while playing basketball.
The Ravens have yet to confirm the news.
This will obviously be a huge loss for the Ravens next season, as not only do they lose the defensive player of the year but an emotional defensive leader as well.
Suggs is coming off an absolute monster season, where he recorded 14 sacks, forced seven fumbles, and even intercepted two passes. One interception was critical in the Ravens win in Pittsburgh last season.
Second-round draft pick Courtney Upshaw will likely fill Suggs' role next season, with Paul Kruger taking over full-time duties at Sam linebacker.
Also look for former second round pick Sergio Kindle to compete for playing time.
