I don’t think you can have official visits in for the Big XII Championship Game.
These might help – from the
NCAA Recruiting Manual:
13.02.15.1 Official Visit
An official visit to a member institution by a prospective student-athlete is a visit financed in whole or in part by the member institution.
13.02.15.2 Unofficial Visit
An unofficial visit to a member institution by a prospective student-athlete is a visit made at the prospective student-athlete's own expense. The provision of any expenses or entertainment by the institution or representatives of its athletics interests shall require the visit to become an official visit, except for the following:
a. The institution may provide complimentary admissions to an on-campus athletics event in which the institution's intercollegiate athletics team competes, in accordance with the provisions of Bylaw 13.7.2.1; and
b. The institution may provide transportation to the prospective student-athlete, when accompanied by an institutional staff member, to view practice and competition sites and other institutional facilities. The institution may provide local transportation to attend one of the institution's home athletics events (on or off campus) during the unofficial visit (see Bylaws 13.02.5.1 and 13.7.3). Payment of any other transportation expenses shall be an institutional violation but shall not cause the visit to become an official visit (see Bylaw 13.5.3).

13.1.7.2.5 Bowl Games
During a dead period, attendance by a prospective student-athlete at the site of an institution's bowl game practice session may occur only if the practice is open to the general public and the prospective student-athlete observes the practice only from an area reserved for that purpose for the general public.
No contact between the prospective student-athlete and institutional staff members or representatives of the institution's athletics interests may occur.
(Adopted: 1/10/92)
13.6.2.4 Visit to Off-Campus Contest
An institution may not provide a prospective student-athlete with transportation to attend an off-campus contest outside a 30-mile radius of the member institution's main campus. However, if an institution is required to play all of its home games in a given sport at a site located in a community other than its own because of conditions beyond its own control (e.g., fire, windstorm, earthquake or other disaster), the Management Council, by a two-thirds majority of its members present and voting, may grant permission to the institution to consider games played at the substitute site as on-campus competition. Violations of this bylaw shall be considered institutional violations per Constitution 2.8.1; however, such violations shall not affect the prospective student-athlete's eligibility.
(Revised: 4/24/03, 8/5/04, 1/9/06 effective 8/1/06)
13.7.2.4 NCAA Championships or Other Postseason Contests
The provision of complimentary or reduced-cost admissions to prospective student-athletes for an NCAA championship (all rounds) or other postseason contests (e.g., bowl game, NAIA or NIT championship) constitutes excessive entertainment and is prohibited. The prospective student-athlete may purchase tickets to such events only in the same manner as any other member of the general public.
