Chargers' Jackson suspended 3 games

SAN DIEGO -- The San Diego Chargers say Pro Bowl wide receiver Vincent Jackson has been suspended by the NFL for the first three games of the 2010 season for violating the league's substance abuse policy.

Jackson pleaded guilty in February to his second DUI since 2006.

"Obviously we're disappointed," Chargers general manager A.J. Smith said in a statement. "Vincent made a mistake and now must deal with the consequences. It's unfortunate, but we'll deal with it and move on."

The suspension was first reported earlier this month by ESPN NFL Insider Adam Schefter.

Jackson will not appeal the suspension, according to a league source.

Jackson has refused to sign his tender as a restricted free agent and could sit out the first 10 games of the season. Under league rules, he will serve the suspension for the first three games of the season, regardless of whether he has signed.
