Joe Looney: I didn't take "cheap shot" at Kevin Williams

San Francisco 49ers guard Joe Looney has insisted that he didn't take a "cheap shot" at Minnesota Vikings defensive tackle Kevin Williams, which caused his injury.

Williams escaped serious harm following the low hit by the offensive lineman during their pre-season clash last week.

"I didn't try to take a dirty cheap shot at him," Looney said told CSN Bay Area. "I was just trying to finish my block. I meant no harm by the block at all."

San Francisco open their regular season campaign against the Green Bay Packers on September 8.
