NEW YORK (AP) - Hall of Famer Dan Dierdorf is retiring from broadcasting after 43 straight years involved with the NFL.

CBS announced Wednesday that he will leave the booth after this season. The 64-year-old Dierdorf has called NFL games for three decades, the longest current tenure by a TV analyst.

He played offensive line for the St. Louis Cardinals from 1971-83, earning All-Pro honors six times. Dierdorf was inducted into the Pro Football Hall of Fame in 1996, and in 2008, he was recognized with the Hall's Pete Rozelle Radio-Television Award. Frank Gifford, John Madden and Len Dawson are the only others to receive both honors.

Dierdorf spent 12 years on ABC's "Monday Night Football" before rejoining CBS in 1999. He currently calls games with Greg Gumbel.

He says travel had become a challenge, adding: "This has been a wonderful ride as I really have lived the dream."
