Arielle Roberson facing ACL surgery

BOULDER, Colo. -- Colorado star Arielle Roberson will have surgery on Wednesday to repair her left ACL, which she tore in a routine drill last week.

A timetable for the junior forward's return won't be determined until her operation.

A two-time honorable mention All-Pac-12 selection, Roberson led Colorado in scoring (12.0) and rebounding (8.3) last season.

Roberson set a Colorado conference tournament game record with 17 rebounds in the 2014 Pac-12 tournament quarterfinals against Stanford.

The 2013 Pac-12 freshman of the year, Roberson has scored 771 points through her first two seasons.
