Kareem Rush paces Missouri with 20.3 points per game.
Tech is led by Big 12 Conference player of the week, Andre Emmett, who averages 19.5 points and a league-best 22.3 points in Big 12 action.
Emmett scored 63 points and grabbed 16 rebounds during wins against Baylor and Colorado last week.
Guard Nick Valdez, who missed the last three games with a left ankle injury, is doubtful for tonight's game.
Tech has four games remaining on its schedule and is in contention for a top four conference finish, which guarantees a first-round bye in next month's Big 12 Tournament.
Tech is tied for fourth in the Big 12 with a 7-5 league record. Missouri and Oklahoma State are also 7-5.
