BOULDER - University of Colorado basketball forwards and siblings Arielle Roberson and Andre Roberson were awarded Athlete of the Week honors on Tuesday for their athletic performances during the week of Nov. 19-25. CU's Athlete of the Week is sponsored by Silk®, Horizon® and International Delight®.

Arielle, a freshman, was named MVP of the Omni Hotels Classic last weekend, becoming the first CU freshman to earn the honor in the 26-year history of the tournament. Roberson led the women's basketball team in scoring (16.5 ppg) and rebounds (7.5 rpg) in the two-game tournament. She had 16 points and a career-best eight rebounds in the win over Texas A&M-Corpus Christi on Friday and had a team-high 17 points on 6-of-11 shooting with seven rebounds, three steals and two assists in the championship game win over San Diego State on Saturday.

Andre recorded his first double-double of the season with 18 points and 13 rebounds, leading the now No. 19 nationally ranked Colorado men's basketball team to an 89-74 home win over Air Force. The junior collected three assists, two blocks and two steals in CU's fifth-straight win of the season. The Buffs are now 5-0 for the first time since the 1989-90 campaign. Colorado is 21-5 when Roberson records a double-double and his 18 points against the Falcons is a season-best. His eight field goals made against Air Force mark a career-high.

The two siblings are from San Antonio, Texas and both attended Wagner High School. This is the first CU Athlete of the Week award of the season for both players.

Also nominated for this week's awards are Alexis Austin (volleyball) and Marques Mosley (football).

Austin, a middle blocker/outside hitter for the volleyball team, recorded 33 kills, including a career-best 19 against No. 2 Stanford last weekend. The freshman helped the Buffs take the first set against Stanford before losing the next three (25-21, 19-25, 13-25, 16-25). Two days later, the Buffs wrapped up their season with a 3-1 loss to Utah. Austin again led the Buffs with 14 kills and hit .316 with just two errors on 38 swings against the Utes.

Mosley had a 100-yard kickoff return for a touchdown in the football team's 42-35 loss to Utah on Friday. It was just the 10th 100-yard play in school history (seven kickoffs, three interceptions). He also added two tackles in the game. The freshman safety ended the 2012 season with 21 kickoff returns for a total of 549 yards, 56 tackles and a quarterback sack. Mosley had a career-high 14 tackles (five solo) earlier in the season against Stanford, a team season-high for 2012.  He was named to the All-Conference honorable mention list and is also a Freshman All-American and Freshman All-Pac 12 candidate.
