49ers Alex Smith and Joe Staley joined the search for 15-year-old Sierra Lamar Saturday.
The search continues for a missing 15-year-old Morgan Hill girl who disappeared near her home three weeks ago.
Volunteers were asked to meet at Burnett Elementary School, located at 85 Tilton Ave. in Morgan Hill early on Saturday morning.
Joining the search for the missing girl were local 49ers' players, including quarterback Alex Smith and left tackle Joe Staley.
Smith has joined previous searches for the teenager and Saturday several of his teammates followed suit.
Over the past three weeks volunteer investigators have also received more than 1,000 tips.
Law enforcement and volunteers have put in hundreds of man hours searching several miles around Morgan Hill.
LaMar's family also announced a $10,000 reward Saturday for information leading to her safe return.
