A day before the 49ers’ preseason opener against the Cowboys, the 49ers announced they will honor the wide receiver throughout the season after he died of ALS in June.

The highlight will come during a nationally televised game against the Rams on Oct. 21 when 350-pound statues of Clark and Joe Montana will be unveiled outside Levi’s Stadium.

Positioned 23 yards apart, the statues will rest, symbolizing the distance by which the two players were separated when Clark made his iconic catch to beat Dallas 28-27 in the NFC Championship Game in January 1982.

In his statue, Clark’s outstretched hands will extend 11 feet into the air. In his statue, Montana will have his arms triumphantly raised.

The 49ers also will wear “87” helmet decals throughout the season, and field bunting at Levi’s will pay tribute to Clark at all games in 2018. In addition, all proceeds from Clark-related merchandise currently in stock at the team store at Levi’s Stadium will be donated to the Golden Heart Fund, which assists the 49ers’ alumni in need.

“Almost four decades ago, Dwight Clark’s miraculous catch launched the San Francisco 49ers into an era of excellence,” 49ers CEO Jed York said. “Since that time, he has served as an inspirational figure to citizens of the Bay Area and beyond. Dwight has meant so much to so many, and it is only fitting that our organization continues to carry on his wonderful legacy.

“The 2018 season provides us a tremendous opportunity to celebrate the life of a very special man, while also raising awareness for the Golden Heart Fund, which was so dear to his heart. Dwight lived his life with great compassion for others, and we want to honor that legacy by raising funds to support his 49ers brothers.”
