John Lynch asked everyone in attendance at the San Francisco 49ers' practice Monday to participate in a 30-second moment of silence to honor victims of the shooting in Gilroy over the weekend.
Three people were killed and 12 others were injured when a man opened fire at the Gilroy Garlic Festival in Northern California late Sunday afternoon.
Lynch -- who's the Niners' general manager -- wanted to honor everyone affected by the tragedy ... so he called for 30 seconds of prayer before SF's training camp workout.
"Our community was affected by a horrific tragedy last night down in Gilroy," Lynch said .
