The Miami Dolphins began their 2026 preseason under new head coach Jeff Hafley, who introduced a new strategic approach and emphasized player growth. Early preparations included the acquisition of offensive lineman Caedan Wallace from the New England Patriots and joint practices with the Washington Commanders.

Following a 26-3 preseason loss to the New York Giants, the team faced several injury setbacks. Linebacker Trey Moore is expected to miss significant time due to an ankle injury, and Ronnie Stanley is unlikely to participate this week due to hamstring issues. Running back Ollie Gordon was medically cleared of a rib injury but did not return to the game. Hafley indicated that the preseason is being used by the coaching staff and general manager Jon-Eric Sullivan to finalize the 53-man roster.

In addition to tactical adjustments, Hafley expressed a desire to reshape the team’s culture. Speaking to the Miami Herald, he noted that the perception of the Dolphins as a ‘soft’ football team ‘eats at my core,’ stating his intention to implement a culture defined by physical play, discipline, and accountability.

As the team prepares for its regular-season opener against the Las Vegas Raiders, Hafley is focusing on a philosophy of thorough weekly preparation to allow players, including rookies, to play ‘free and fearless.’ He also addressed external criticisms regarding the team’s projected performance, encouraging players to use outside doubt as motivation.
