Siena remain fourth in the Serie A table after coming from two goals down to draw 2-2 with Parma.
The Gialloblu had started well at the Stadio Artemio Franchi, taking the lead through Domenico Morfeo (35).
They doubled their advantage in the second half through Igor Budan (70) before the Tuscan club started their fightback.
Albania international Erjon Bogdani (pictured) made it 2-1 seven minutes later before striking the equaliser in injury time to claim a share of the spoils.
A second-half strike by Giorgio Corona (68) gave Catania a 1-0 win at bottom club Reggina in the other Serie A match on Saturday.
