The Detroit Pistons equalled the longest losing run in NBA history as they were beaten by the Boston Celtics for a 28th consecutive defeat. Detroit, who lost 128-122, matched the record set by the Philadelphia 76ers across the 2014-15 and 2015-16 seasons. The Pistons led by 21 points at one stage against the Celtics but went on to lose in overtime. They face the Toronto Raptors on Saturday aiming to avoid taking sole ownership of the losing record. Detroit became the first team to lose 27 straight games in a single season when they fell to a 118-112 defeat by the Brooklyn Nets on Tuesday.
