AMIENS, France, May 6 (Reuters) - Paris St Germain needed a late goal from substitute striker Yannick Boli to win 1-0 at second division Amiens and advance to the French Cup final on Tuesday.
The match was interrupted after just over 30 minutes when teargas was sprayed from a section of the stands filled with PSG fans. It resumed after a 10-minute break.
The 20-year-old Boli hit the back of the net after a brilliant solo run 12 minutes from the end.
PSG, who often make unwanted headlines because of their unruly supporters, are third from bottom in the league with two matches left and in danger of being relegated for the first time.
Ligue 1 leaders Lyon, chasing their first League and Cup double, host second division Sedan in the second semi-final on Wednesday.
