BUENOS AIRES, April 29 (Reuters) - Controversial referee German Delfino has been re-instated for the first leg of the Libertadores Cup's last-16 tie between River Plate and Boca Juniors after serving a suspension for a "messy" decision reversal in an Argentine league match.
Delfino sparked ire from Velez Sarsfield after over-turning his own handball decision that awarded the Argentine team a penalty and saw Arsenal defender Daniel Rosero Valencia sent off three weeks ago.
Just before the penalty was taken, Delfino was apparently alerted by his linesman that it was Rosero Valencia's opponent Pavone who had handled the ball, prompting the referee to call the Arsenal defender back much to Velez's fury.
