49ers running back Raheem Mostert plans to take his one-year tender as a restricted free agent, according to his agent.

The 49ers and Mostert's agent, Brett Tessler, spoke this offseason about a multi-year contract extension. However, Mostert figures to play out the season to become an unrestricted free agent a year from now.

"After discussions with the San Francisco 49ers about a multi-year deal for RB Raheem Mostert, we decided to take the Restricted tender and look forward to a great 2019," Tessler wrote on Twitter.

Mostert has yet to sign the tender and is still able to negotiate with other teams until April 19. If another team signs Mostert to an offer sheet, the 49ers would have the right of first refusal to match the deal to retain him.

Mostert is scheduled to earn $2.025 million this season as a fourth-year professional. He is expected to serve as the team's No. 3 running back behind Jerick McKinnon and Matt Breida, while also contributing on all special teams.

Mostert proved to be a valuable backup running back, as well as one of the best special-teams players in the league. Mostert saw action in nine games before sustaining a fractured forearm against the Raiders. He averaged 7.7 yards a carry on 34 rushing attempts.
