Context:
In July 2021, after 25 seasons as members of the Big 12, Texas and rival Oklahoma accepted invitations to join
the Southeastern Conference (SEC) no later than the 2025 season. In February 2023, the Big 12 announced that the
two schools had negotiated a combined $100 million early termination fee in order to leave for the SEC a year
before the schools' media rights deal with the Big 12 was set to expire. The Longhorns football team will
continue competing in the Big 12 through the 2023 season before moving to the SEC in 2024.

Input:
What team other then Texan Longhorn accept an invitation to the SEC in July 2021?

Output:

Based on the context provided, the only other team from outside the SEC that 
accepted an invitation to join the conference was Oklahoma. The information 
states that after Texas and Oklahoma accepted their invitations to join the SEC,
the Big 12 announced that the two schools had negotiated a combined $100 million
early termination fee in order to leave for the SEC a year before the schools' 
media rights deal with the Big 12 was set to expire. This implies that the Big 
12 was losing two of its most prominent members, and the context does not 
mention any other team from outside the SEC accepting an invitation to join the 
conference at that time.
