Referee Michael Dean holds a yellow cards after booking both Chelsea's Diego Costa, right, and Arsenal's Gabriel during the English Premier League soccer match between Chelsea and Arsenal at Stamford Bridge stadium in London, Saturday, Sept. 19 2015. — AP LONDON — Arsenal defender Gabriel was given a one-match ban by the Football Association Friday after accepting a charge of improper conduct following his controversial dismissal at Chelsea. Gabriel was sent off for kicking out at Chelsea forward Diego Costa in the Gunners' 2-0 defeat at Stamford Bridge last weekend. The FA announced Tuesday it had accepted Arsenal's challenge to referee Mike Dean's decision and withdrawn the three-match suspension as replays showed he didn't make contact with Costa, but the Brazilian defender has not escaped all punishment. Gabriel had protested angrily and briefly refused to leave the pitch following the fall-out from his clash with Costa and his new punishment for that behavior means he will now serve a one-match ban at Leicester this weekend. The news is a blow to Arsenal ahead of the trip to in-form Leicester, but manager Arsene Wenger had already admitted earlier Friday that he expected a new ban for Gabriel. — AP
