Clausura title hopefuls River Plate suffered a shock setback as Belgrano claimed a 2-1 home victory at El Gigante de Alberdi on Monday night.

A three-point haul from River's trip north would have lifted the 35-time Argentinian champions two clear at the top.

But, although Teofilo Gutierrez cancelled out Jorge Velasquez's opener, Lucas Zelarrayan found a winning goal for 13th-placed Belgrano with five minutes remaining.
