The 29-year-old Baltimore Ravens linebacker, who suffered the injury during a conditioning test, will have the surgery next week and anticipates returning to his team's lineup in about four to six months.
"Absolutely," Suggs said in a report posted on The Carroll County Times' website. "Middle to end of October. Definitely beginning of November."
The loss of Suggs for any amount of time would be a major blow to a defensive-oriented Ravens team that captured the AFC North division title last season and came within one victory of a berth in the Super Bowl.
Suggs had a career-high 14 sacks last season along with 70 tackles and two interceptions.
"He will see a specialist early next week, and we'll know more at that time," the Ravens said in a statement.
