[CONCACAF CHAMPIONS LEAGUE] It’s happened before and Tuesday night it has happened again: a valiant performance by an MLS team in Mexico merits respect yet doesn’t earn points. A bizarrely disallowed goal added another dose of Mexican misfortune to this match.

The Columbus Crew held out against Santos Laguna until the third minute of stoppage time, but couldn’t stop Ivan Estrada from drilling a low shot past keeper Andy Gruenebaum that provided Santos with a 1-0 victory in the second Concacaf Champions League game for both teams in Group B.

Santos (2-0-0) takes over first place in the group; the Crew (1-1-0) is in second and will stay there no matter what the outcome when pointless Municipal and Joe Public play on Thursday, after which group play resumes in mid-September.

The loss was the 16th in 18 matches by a side from Major League Soccer, who have only managed two draws against Mexican teams in Mexico.

Midway through the first half, Emilio Renteria went off to have a bleeding facial wound bandaged up, and came back on wearing a clean jersey without a number.

When Andy Iro headed in Renteria's cross, Panamanian referee Luis Rodriguez consulted with his linesman and cautioned Renteria while disallowing the goal.
