UFC legend Cain Velasquez was just denied bail again ... after the man he's accused of shooting back in February claimed he suffered serious injuries in the alleged attack.
A Santa Clara County judge denied Velaquez's request for bail in a courtroom on Monday ... following a nearly one-hour-long hearing.
During the proceedings, Velasquez's attorneys argued -- according to reporter Nolan King -- that the 39-year-old should be granted bail ... and said the former fighter would be willing to post $1 mil as well as have full-time supervision and/or electronic monitoring while out from behind bars.
