San Francisco grad transfer Mark Tollefsen officially became an Arizona Wildcat today, with the school announcing his addition via Twitter.

UA did not issue a news release on Tollefsen or have a comment from UA coach Sean Miller, but a spokesman said the school has received financial aid paperwork that made his transfer official. Four-year transfers do not sign letters-of-intent.

Tollefsen will wear No. 23 for Arizona, while the Wildcats also announced Kadeem Allen will exchange his No. 20 for Stanley Johnson's old No. 5. The incoming freshmen will wear the following numbers:

No. 2 Ray Smith

No. 3 Justin Simon

No. 11 Allonzo Trier

No. 21 Chance Comanche
