Former Oakland assistant Curtis Fuller will be Slocum's assistant, according to the team. Fuller was a Packers safety in 2003 and 2004.
Slocum was the Packers' assistant special teams coach for three seasons under Mike Stock, who announced his retirement earlier this month. Green Bay coach Mike McCarthy has yet to announce a replacement for fired defensive coordinator Bob Sanders, although the favorite might be St. Louis interim coach Jim Haslett.
UPDATE: The Rams announced Thursday that Haslett will not be retained, making him available to join the Packers or any other team.
