Huntington Beach (Calif.) Edison linebacker Jordan Zumwalt was a commit to Stanford since the spring.
But the month of January saw him wavering between the Cardinal and UCLA and USC.
On Wednesday morning, Zumwalt picked the Bruins.
"I'm going to UCLA," said Zumwalt.
The four-star linebacker is the second Charger in three years to commit to the Bruins, joining former Edison teammate Nick Crissman, a redshirt freshman quarterback for the Bruins.
