SANTA CLARA, Calif. -- Former San Francisco 49ers lineman Clay Matthews Sr., who was the patriarch of a famous football family, has died. He was 88.

The 49ers said Matthews died Thursday. He had been dealing with a long illness.

Matthews was a two-way player for San Francisco for four seasons in the 1950s. He played in 45 games and missed two seasons while serving in the Korean War.

Five of Matthews' grandsons have also played in the NFL, including Green Bay linebacker Clay Matthews III and Atlanta offensive lineman Jake Matthews.
