The 49ers will bring in some training camp kicking relief for Andy Lee and Phil Dawson.
The team has agreed to terms with former UC Davis punter Colton Schmidt, who averaged a school-record 44.5 yards per attempt last season.
Schmidt had a tryout with the 49ers last month and impressed coaches, including special-teams coach Brad Seely. Schmidt also can handle kickoffs, his agent said Wednesday, and he likely will help with kicking and punting duties this summer. Schmidt had 41 touchbacks on kickoffs and punts combined last season.
Schmidt and the rest of the 49ers' rookie class will report for training camp July 19. The rest of the team will report six days later. The 49ers had an open roster spot to sign Schmidt.
Ambassador Whitner Safety Donte Whitner is part of an NFL contingent that will travel to London next week in advance of the NFL games being played there this season. Whitner and the 49ers will face the host Jacksonville Jaguars on Oct. 27.
The other players are Jared Allen and Kevin Williams of the Minnesota Vikings, Uche Nwaneri of the Jaguars and Ramon Foster of the Pittsburgh Steelers.
On Tuesday, the group will meet with reporters at Wembley Stadium and visit radio studios. On Wednesday, they will be in Birmingham for a "chalk talk" stage show for fans.
Vernon Davis was the 49ers' ambassador in 2010 before the team hosted the Denver Broncos.
