ESPN broadcaster Joe Buck stepped in as a guest co-host on ABC's Good Morning America on Tuesday, July 28, 2026, sitting alongside regular anchors Robin Roberts and George Stephanopoulos in place of absent co-host Michael Strahan.
The network had previously promoted Buck's guest appearance during its Monday broadcasts, signaling a planned temporary absence for Strahan.

ABC did not announce any formal changes to Strahan's regular role on the morning news program.
Buck is best known as the lead play-by-play announcer for ESPN's Monday Night Football, a position he assumed in 2022 alongside broadcasting partner Troy Aikman after nearly three decades at Fox Sports calling NFL games and the World Series.
Outside of sports broadcasting, Buck has hosted Jeopardy! and the competition series Domino Masters.
Off the air, Buck is married to ESPN features reporter and former Denver Broncos cheerleader Michelle Beisner-Buck, whom he wed in 2014.
Beisner-Buck spent six seasons cheering for the Broncos, including appearances at the 1998 Super Bowl and 1999 Pro Bowl, before transitioning into sports journalism with NFL Network and ESPN.
The couple shares six-year-old twin sons, Wyatt Joseph and Blake Andrew, born on April 26, 2018, following three rounds of in vitro fertilization.
"It took us a long time to get to this point," wrote Michelle Beisner-Buck. "There is not much that's more financially, emotionally, physically taxing than in vitro fertilization.
It is a very grueling, gnarly process.
