Larry Grant, a 49ers backup linebacker the past two seasons, has been suspended the first four games of the 2013 season for violating the league's policy on performance-enhancing substance, the NFL announced Friday.

Grant, a five-year veteran, is an unrestricted free agent and remains eligible to participate in all offseason and exhibition-season actions upon joining a team.

Last month, the 49ers signed Grant's potential replacement as Patrick Willis' backup in former Cincinnati linebacker Dan Skuta.

Grant was a key member of the 49ers special teams.

  • Cincinnati reached agreement on a two-year deal with former Pittsburgh linebacker James Harrison, said his agent, Bill Parise.
