Alvaro Morata gave Milan the lead early in the second half.
AC Milan were held to a 1-1 draw at home by relegation-battlers Cagliari on Saturday in new coach Sergio Conceicao’s Serie A debut.
The hosts dominated the entire match but the game was goalless at halftime before Alvaro Morata broke the deadlock in the 51st minute from close range.
Cagliari stunned the hosts four minutes later from a counter-attack with defender Nadir Zortea scoring with a low shot from outside the box.
Milan sit eighth in the standings on 28 points, eight points behind fourth-placed Lazio, but with two games in hand. Cagliari are 18th with 18 points.
