Eddie Williamson undergoes angioplasty

FORT WORTH, Texas -- TCU offensive line coach Eddie Williamson underwent angioplasty at an area hospital Saturday after experiencing chest pains on the sideline during the first half of the No. 3 Horned Frogs' 40-35 win over San Diego State.

Head coach Gary Patterson said the 58-year-old Williamson was removed from the field quickly and taken to a Fort Worth hospital Saturday. Patterson said Williamson was in stable condition.

Center Jake Kirkpatrick said most players weren't aware Williamson had fallen ill. He said the coach is "like a dad to all of us."

Williamson is in his 10th season at TCU after joining the Frogs one year after Patterson was promoted to head coach. He was made assistant head coach in 2002.
