Minnesota Vikings' rookie quarterback J.J. McCarthy has undergone a second knee surgery, and his timeline for return is now in a much worse spot than before.

Kevin Seifert of ESPN.com reports that McCarthy had a second surgery on his right knee. McCarthy’s first surgery was to repair a torn meniscus and the second operation was needed to address swelling the first-round pick was experiencing after increasing his rehab work. McCarthy also received a biologic injection to deal with the issue.
