ESPN's Chris Mortensen has reported that Patriots safety Rodney Harrison will be suspended for four games by the NFL after he admitted to federal investigators that he obtained Human Growth Hormone (HGH).

Harrison had a hearing with NFL commissioner Roger Goodell on Friday, the sources said, and the Patriots could announce the suspension as early as Saturday, when all teams must reduce their rosters to the regular-season limit of 53 players.

A league spokesman said Friday the NFL will not comment on the Harrison case. Harrison could not be immediately reached for comment. A Patriots source told ESPN.com's Len Pasquarelli that the team is aware of the sanction against the 13-year veteran and is "dealing with it." The team source declined to say when the Patriots became aware of Harrison's involvement.
