MIAMI, Florida — The Miami Dolphins entered the final stage of training camp believing their young defensive centerpiece was ready to take another major step forward in 2026.
Instead, the team is now facing uncertainty after one of its most important young defensive players suffered a concerning injury during preseason action, forcing Miami to reconsider its immediate plans before the start of the regular season.
The injury occurred during the Dolphins' recent preseason matchup against the Washington Commanders.
During the game, the young defensive lineman went down after a physical play in the trenches. Although he was able to leave the field without being carried off, the Dolphins immediately took a cautious approach and began further medical evaluations following the game.
After additional testing, the team's medical staff determined that the injury would require an extended recovery period.
The Dolphins have since confirmed that the player will miss this week's joint training camp sessions with the New York Giants, a major preparation opportunity before the regular season begins.
The player at the center of the situation is Kenneth Grant, Miami's first-round selection in the 2024 NFL Draft out of Michigan.
Grant entered the NFL with enormous expectations after becoming one of the most dominant interior defensive prospects in college football. His rare combination of size, strength, and athletic ability made him viewed as a potential long-term cornerstone for the Dolphins' defensive front.
However, this latest setback has created a difficult situation for Miami's coaching staff.
According to the team's medical evaluation, Grant is expected to need at least four more weeks to recover, meaning he is projected to miss the upcoming joint practices with the Giants and could be unavailable for at least the opening game of the 2026 regular season.
For head coach Jeff Hafley, the timing creates a significant challenge.
With roster decisions approaching and the regular season just around the corner, Hafley is now evaluating how the Dolphins should handle the defensive tackle position and whether adjustments need to be made to the starting lineup.
"Kenneth is a huge part of what we want to build here. But the most important thing is making sure he comes back healthy and ready to compete. We are going to be smart with this process and make the decision that gives him the best chance to succeed," Hafley said while addressing the injury situation.
Grant's absence represents a major blow for a Dolphins defense that expected him to immediately become one of the team's most impactful interior defenders.
His ability to control the line of scrimmage, absorb double teams, and create pressure from inside was expected to transform Miami's defensive identity in 2026.
For a player carrying the expectations of a first-round selection, this injury arrives at a difficult moment.
The Dolphins remain hopeful that Grant can return early in the season, but the next several weeks will determine when he can safely reclaim his role as one of the foundations of Miami's defense.
For Miami, this is more than missing a player during training camp.
It is a test of depth, patience, and preparation as the Dolphins wait for one of their brightest young defensive stars to make his return.
