HOUSTON (AP) - Corey Frazier and Klein Kubiak are teammates at Rice and friends off the field.

But on Sunday they'll be pulled in different directions. Their fathers - Minnesota Vikings coach Leslie Frazier and Houston Texans coach Gary Kubiak - will be on opposite sidelines.

Corey says Klein told him last Sunday that the two, ``were enemies from here on out this week.''

They have become close in their time at Rice after bonding over the shared experiences of growing up with fathers who coached in the NFL.

Klein, a junior receiver, and Corey, a senior safety redshirting after an injury, will return to being friends after Sunday's game as Rice prepares for its first bowl appearance since 2008 when it faces Air Force in the Armed Forces Bowl on Dec. 29.
