The NFL suspended Jackson four games for multiple violations of unnecessary roughness rules, Tom Pelissero of NFL Network reports.
Jackson has already been fined multiple times this season, and his latest hit to the head and neck area of Packers rookie TE Luke Musgrave on Sunday was the league's final straw and led to Jackson's month-long ban. Jackson is appealing the suspension, according to Ian Rapoport of NFL Network, so it's possible he gets a game knocked off. For the moment, Jackson isn't eligible to play again until Week 13 against the Texans. P.J. Locke is expected to fill in as the starting safety next to Justin Simmons for Denver.
