BARCELONA—Andres Iniesta’s serious knee injury overshadowed another stellar performance by Lionel Messi on Saturday, when the Barcelona forward scored a second goal in stoppage time to earn a 3-2 win at Valencia.

The hotly contested game was marred both by Enzo Perez’s tackle that forced Iniesta off on a stretcher and a fan throwing a water bottle at Barcelona’s players while they celebrated Messi’s winner. The bottle appeared to strike Neymar’s head and also impact other Barcelona players when it was tossed into their tight huddle.
