The victim was taken Monday to a local hospital with non-life-threatening injuries, according to the San Jose Police Department.
Police provided few details, other than saying the incident occurred near the intersection of Monterey Highway and Bailey Avenue. CNN has requested a police report but had not received one by Tuesday afternoon.
“The motive and circumstances surrounding this incident are still under investigation at this time,” San Jose police said.
Delaney Murray of the Santa Clara County District Attorney’s Office said, “Our Office has not received the police report yet to review and therefore have no information on Mr. Velasquez. No charges have been filed at this time.”
A jail entry indicated there was no bail set and a court hearing was possible for Wednesday.
The mixed martial arts professional had 12 wins by knockout, two by decision and two title defenses, according to his UFC profile. Velasquez had three losses.
