Thirty-seven members of that 1981 Super Bowl champion squad returned to pay tribute, along with former team owner Eddie DeBartolo Jr., the Mercury News reported.
Clark is best known for his 6-yard grab with 58 seconds left against the Dallas Cowboys in the NFC Championship Game on Jan. 10, 1982.
The 49ers would win five Super Bowls, but the catch and victory was the springboard for the team’s future successes.
“He’s very well known to all you 49ers fans and, oh, yeah, to you Cowboys fans, too,” said Hall of Fame quarterback Joe Montana, who threw that game-winning pass. “Any time you turn on the NFL and you’re watching TV, you’ll see him flying high in the back of that end zone and making one of the most iconic catches in NFL history.”
