Pro Football Hall of Famer and former television actor Merlin Olsen has died. He was 69.

Utah State University assistant athletic media relations

director Zach Fisher says Olsen died Wednesday night.

Olsen was an All-American at Utah State and a first-round draft

pick of the Los Angles Rams in 1962.

He was part of the Rams’ “Fearsome Foursome” defensive line,

which set an NFL record for the fewest yards allowed during a

14-game season in 1968.

Olsen is still the Rams’ all-time leader in career tackles with

915.

Olsen moved on to acting with roles in “Little House on the

Prairie” and later his own series, “Father Murphy,” which ran

from 1981 to 1983.

He was diagnosed with mesothelioma last year.
