Barcelona's 1-0 La Liga victory against Celta Vigo on Sunday evening featured one of the most bizarre incidents of the season so far. With the score at 1-0 following Jeremy Mathieu's 73rd minute header, tempers flared between Celta striker Fabian Orellana and Sergio Busquets as the Barcelona midfielder attempted to waste time during the closing stages. Orellana remonstrated angrily with the match officials before grabbing a lump of grass from the floor and throwing it in the direction of Busquets.

Referee Inaki Vicandi Garrido decided the incident was enough to warrant and straight red card and promptly gave Orellana his marching orders.
