Jackson says he's 100 percent healthy, Jamison Hensley of ESPN.com reports.
Jackson returned to practice Aug. 24 after missing a couple days with a minor groin injury. There's been no report of trouble since that time, so he should be all set for a Week 1 home game against Cleveland. His two matchups with the Browns last year produced 486 passing yards, 169 rushing yards, six passing TDs and three turnovers.
