English Premiership side Sale Sharks are "fighting legal action" by former player CILLIAN WILLIS, who claims the club "mishandled the injury that forced him to retire at 28." The former scrum-half was knocked out in an LV Cup game against Saracens in '13 "before being allowed to play on by Sale’s medical team." He was later replaced but was told to "never play again after suffering previous concussions." Willis is believed to be the first to take legal action against a Premiership club "for medical negligence and the case could set a precedent" (London DAILY MAIL, 8/20). ... RUUD GULLIT said that he will "replace DICK ADVOCAAT on DANNY BLIND's Netherlands coaching staff." Advocaat agreed to become Blind's assistant in May but "left earlier this month when he was offered the chance to take charge at Turkish club Fenerbahce." Former Netherlands player Gullit, who has been out of management since his brief stint in charge of Russian side Terek Grozny in '11, has said that "he will now take on a role ahead of the 2018 World Cup qualifiers" (ESPN.com, 8/22).
