Oakland Raiders linebacker Vontaze Burfict’s appeal to overturn his suspension for the rest of the year for a helmet-to-helmet hit was denied Wednesday.

Appeals officer Derrick Brooks ruled he would not reduce the longest suspension ever handed down for an on-field infraction. Brooks is appointed jointly by the NFL and the NFLPA and heard Burfict’s appeal of the ban for the final 12 games of the regular season and the playoffs.

Brooks upheld the decision handed down last week by NFL Vice President of football operations Jon Runyan to punish Burfict severely for “repeated violations of unnecessary roughness rules” after the latest hit on Indianapolis tight end Jack Doyle on Sept. 29.

The suspension is without pay, costing Burfict more than $1.1 million in salary and per game active roster bonuses.
