Washington OLB Ryan Kerrigan left Sunday's game against the Bucs early with a broken hand and won't return. Washington gets a bye in Week 8, so we'll see if Kerrigan's playing with a club after that. His absence should create more playing time for promising rookie OLB Preston Smith.

Washington OLB Ryan Kerrigan had arthroscopic surgery on his left knee Tuesday, according to ESPN.com's John Keim. Kerrigan called it "cautionary" and said that the knee needed to be cleaned up to avoid potential issues later on. Doctors will check the knee next week and determine how long he'll be out. Washington's 1st full-team minicamp is set for June 16-18. We'll see how soon Kerrigan can get back onto the field before determining whether this surgery will alter his outlook for the 2015 IDP rankings. Kerrigan led the team with a career-high 13.5 sacks last season.
