University of Santo Tomas took over the spot of National University in the Shakey's Super League National Invitationals unwrapping on 29 July at the FilOil EcoOil Center in San Juan.

League organizer Athletic Events and Sports Management Inc. president  Ian Laurel confirmed that the Lady Bulldogs are skipping the tournament featuring 12 of the finest college teams in the country due to another commitment.

The University Athletic Association of the Philippines Season 85 runner-up is currently in talks with the Philippine National Volleyball Federation for a series of international stints.

NU, however, expressed its intention to join the second installment of the SSL Collegiate Preseason Championship to defend its crown.

"Although they (NU) submitted their requirements, they told us that they were talking with the PNVF. They have I think three tournaments that need the national team to join so they're looking at partnering with NU," Laurel told Daily Tribune.

"They told us that if they could work out a partnership with the PNVF they would have to beg off from the Invitationals and just join the Preseason."

Laurel added that Lady Bulldogs' management has already informed them of the recent developments.

"I think they've already sealed a partnership (with the PNVF) because I got word from NU management last week that they're not joining the Invitationals," the ACES head said.

Newly-appointed NU head coach Norman Miguel also confirmed that the Lady Bulldogs have already committed to the PNVF partnership.

The league intended to have the top three teams of the UAAP join the podium finishers of the National Collegiate Athletic Association Season 98 along with the two qualifiers each from Luzon, Visayas and Mindanao for the National Invitational.

The Lady Bulldogs' withdrawal opened a spot for the UAAP Season 85 fourth placers Tigresses to join defending champion De La Salle University and bronze medalist Adamson University.

"We're able to talk to them (UST) and they agreed. They are now in the process of submitting their documents," Laurel said.

The Tigresses are expected to field their holdovers led by Regina Jurado, Renee Penafiel and setter Cassie Carballo along with new recruits as the squad rebuilds following the departure of ace scorer Eya Laure, Imee Hernandez and Milena Alessandrini.

Also in the field are NCAA back-to-back champion College of Saint Benilde, second placer Lyceum of the Philippines University and University of Perpetual Help System Dalta.

Enderun College and De La Salle University-Dasmariñas are the Luzon qualifiers, University of Southern Philippines Foundation and University of San Jose-Recoletos are representing the Visayas while Mindanao will be bannered by Notre Dame of Dadiangas University and Jose Maria College of Davao.
