With Joseph Valtellini vacating the GLORY welterweight title due to post-concussion syndrome, GLORY announced a welterweight battle between Nieky Holzken and Raymond Daniels for the vacant title at GLORY 23 in Las Vegas on August 7, 2015.
In an unfortunate turn of events, "Bazooka" Joe Valtellini was forced to abdicate his GLORY welterweight crown on Thursday (June 4, 2015) due to ongoing issues from post-concussion syndrome.
Valtellini last fought at GLORY: "Last Man Standing" last June and a rematch between him and the GLORY 19 "contender" tournament winner Nieky Holzken has long been in discussion to be made at some point in 2015.
