Stock index futures fell on Friday, with many investors expecting the May payrolls report to show more weakness in the economy, confirming recent data signaling the economic recovery is faltering.

U.S. employment gains probably lost steam in May as high energy prices and the supply chain effects of Japan's earthquake and tsunami bogged down the economy.
