It's the second week in a row and third time this year that Jank has been honored as the top freshman.
In two games last week, Jank averaged 21.0 points and 9.0 rebounds per game. She also made 60 percent of her shots from the floor (15-for-25) and 90.9 percent of her free throws (10-for-11).
Jank had 26 points and seven rebounds in a loss to Dartmouth and posted her fourth double-double of the season (16 points, 11 rebounds) in a win against Air Force.
Since joining the conference in 2011, CU has had nine freshman of the week honors. Arielle Roberson was honored five times during the 2012-13 season, Kennedy Leonard once in 2015-16 and Jank three times this year.
Oregon's Sabrina Ionescu was named the Pac-12 player of the week. Her week included her seventh career triple-double, breaking the Pac-12 career record.
CU will return to the court Thursday at 7 p.m. with a home date against Westminster (Mo.) College.
