Karl Toko Ekambi scored his second goal for Lyon in the Ligue 1 but it was enough to save them from a 2-1 loss against Nice.
The Cameroon striker who completed a temporary return to France last month, made his second league outing on Sunday and drew Rudi Garcia's side level on the stroke of half-time.
Toko Ekambi's effort could not prevent his team from suffering their first defeat in 10 games as Dolberg's double propelled Nice to avenge their 2-1 loss to Lyon in a French Cup fixture on Thursday.
