Most significant move: The San Francisco 49ers released long-snapper Brian Jennings eight days before Jennings would have set a franchise record for consecutive games played. Jennings had been with the team since 2000 and was the longest-tenured current 49ers player. Undrafted free agent Kevin McDermott will handle snapping duties heading into the regular season. Coach Jim Harbaugh had called the snapping competition close, an indication the 49ers were thinking about going younger and cheaper at a position that can be taken for granted.
