Hamilton Academical claimed their first win at Celtic Park since 1938 as they beat champions Celtic 1-0 to top the Scottish Premiership table.
Hamilton midfielder Ali Crawford made the breakthrough four minutes into the second half after the Celtic defence failed to deal with a Stephen Hendrie cross into the box.
Celtic squandered a number of chances to equalise as manager Ronny Deila, who has struggled since taking over from Neil Lennon during the close season, was booed at the final whistle.
Table-toppers Hamilton, who were promoted from the Scottish Championship (second tier) last season, have 20 points from nine games, while Celtic are sixth with 14 points from eight matches.
