Miles adding former Cowboy to staff

(Stillwater-AP) -- Oklahoma State football coach Les Miles is adding a former Cowboy to his coaching staff.

Miles is hiring Josh Henson as tight ends coach, making him the fifth assistant on the O-S-U staff.

Henson was a four-year letterman at Oklahoma State and a starter on the 1997 team that played in the Alamo Bowl.

Meanwhile, O-S-U's defensive coordinator for the past two years has landed a job with a Big 10 school.

Mike Cassity is joining the staff at Illinois as defensive coordinator.
