Spain's anti-doping agency investigating Nasri (The Associated Press)

Spanish club Sevilla says the national anti-doping agency is looking into reports that midfielder Samir Nasri recently had intravenous treatment at a Los Angeles clinic. Sevilla spokesman Jesus Gomez told The Associated Press on Friday that ''the agency has been in contact with the club to ask for information'' about the player. A spokesman for the anti-doping agency told the AP that its investigators are checking whether any treatment Nasri may have received had steered clear of the list of prohibited substances.
