The top two in the Top 14 table could not be separated as Clermont Auvergne and Toulouse shared a thrilling draw.
Top 14 leaders Clermont Auvergne were stunned by a thrilling Toulouse comeback as the division's top two shared a 20-20 draw.
Franck Azema's side boasted a 17-3 half-time lead but contrived to throw away that advantage as the spoils were shared at the Parc des Sports Marcel Michelin.
First-half tries from Apisai Naqalevu and Peter Betham helped put the hosts into a commanding position at the break.
But a Greig Laidlaw penalty was all they had to show for their second-half efforts, as Matthis Lebel and Romain Ntamack touched down for Ugo Mola's men.
It was left to Thomas Ramos to kick a last-gasp penalty to earn a memorable draw for Toulouse, but their celebrations were somewhat dampened by a serious-looking leg injury for Selevasio Tolofua.
