What a week. What a mess. Two games abandoned due to off-field shenanigans casts something of a pall over proceedings. First, the game between Emelec and Olimpia was abandoned with nine minutes remaining after a shower of missiles rained down on visiting goalkeeper Martin Silva. Prior to that, Richard Ortiz had put Olimpia in front, getting on the end of a lovely, flowing move that ripped the middle our of Emelec. Half way through the first half, Pablo Zabellos was found with a great through-ball and slammed it high into the roof of the net for 2-0. Emelec came back into it after the break and, after spurning a few good chances, Jose Franco slipped one between Silva's legs to reduce the deficit. Raul Caceres picked up a second yellow late on to leave Olimpia a man short before the shower of bottles - an apparent protest against coach Juan Ramon Carrasco - forced the referee's hand. The result stands as is and Olimpia progress.
A day later, the game between Nacional and Universidad de Chile didn't even make it to half-time. Universidad were already 2-0 up by that point as Eduardo Vargas and Matias Rodriguez opened up a porous defence when a till roll struck one of the assistant referees on the head. Again, the result stands and Universidad go through.
Elsewhere, Bolivians Aurora thrashed Nacional Asunción despite going behind to Rodrigo Teixeira early on. Jair Reinoso equalised and a penalty from Diomedes Peña put Aurora in front. Teixeira's second levelled it up, but Aurora kicked on and were back in front before the break through Fernando Sanjurjo and late goals from Augusto Andaveris and Jaime Cardozo wrapped up a big win.
Single-goal wins were enough for LDU Quito - Luis Bolaños for the Ecudorians against ten-man Trujillanos - and Libertad - Ignacio Canuto with the only goal - against La Equidad as they both backed up first-leg wins in some comfort.
Drama in the all-Colombian tie between Deportivo Cali and Santa Fe as they battled to a second successive 1-1 draw. Juan Roa's own goal put Deportivo in the lead, but Sergio Galvan Rey levelled it up twenty minutes from time. Hurnan Burbano was the only player to miss in the resultant shoot-out and Santa Fe go through.
