COLORADO SPRINGS, Colo. — Colorado State, BYU, New Mexico and San Diego State won Mountain West player of the week honors Monday.

CSU wide receiver Johnny Walker won the honor on offense and BYU linebacker Kelly Poppinga won for defense.

New Mexico kicker John Sullivan and SDSU kicker returner Mekell Wesley shared the special teams award.

Walker had seven catches for 177 yards and two touchdowns in the Rams' 26-23 loss at New Mexico. His 64-yard touchdown reception in the first quarter was the longest reception of his career, and his passing yardage was the second-highest in the MWC this year.

Poppinga had a career-high 17 tackles, seven of them solo, and an interception in the Cougars' 27-22 victory over TCU. He had wad tackle for loss (four yards) and was credited with a quarterback hurry. It was most tackles by a BYU defender in a single game since Rob Morris had 17 tackles against San Diego State in 1998.

Sullivan hit the game-winning field goal from 43 yards as time expired in the Lobos' victory over Colorado State. He had four field goals total, tying his career best, including a 46-yarder, the longest in his career. He leads the nation with 23 field goals this season, a UNM record, and it ties the conference record set by Colorado State's Jeff Babcock in 2002.

Wesley returned five kickoffs for 178 yards, including an 89-yard touchdown, as the Aztecs beat UNLV 38-30 win at UNLV. His total return yardage is second in SDSU single-game history. Wesley's return for a touchdown was the first in the Mountain West this season and the first for the Aztecs since 1997. His five returns gave San Diego State an average starting field position of the 36-yard line, which is an Aztecs best since Oct. 29, 2005.
