The Will McDonald Jets role question became more immediate when Joseph Ossai suffered a foot injury in the final preseason game. McDonald is listed directly behind Ossai in one EDGE lane on the team’s unofficial communications depth chart, which puts the connection in plain view. It does not give McDonald a promotion or a defined workload. It gives the Jets a current reason to test whether his best trait can fit inside a broader defensive job.
McDonald’s pass rush is the obvious starting point, but the size of his role may depend on how reliably he handles run defense and other assignments. Week 1 can begin to show how Aaron Glenn intends to use him without settling the question.
What Joseph Ossai’s Injury Changes
Ossai ruptured the plantar fascia in one foot during the final preseason game against the Giants. Glenn described him as week to week. That makes his status relevant to the immediate EDGE rotation without supplying a return date or a Week 1 answer.
For McDonald, the injury sharpens an existing opportunity question. The Jets may need flexibility from the players in Ossai’s lane, and McDonald is the next name in that lane on the communications chart. The useful issue is not whether he inherits a job. It is whether the defense can access his pass rush in enough situations while asking him to handle the rest of the position.
A pass-rush specialist can affect selected downs or packages. A defender trusted across down, distance and personnel groupings gives a coordinator more freedom to keep him on the field without advertising a narrow purpose. Ossai’s injury makes that distinction more urgent, but it does not resolve it.
Where Will McDonald Sits on the Depth Chart
The unofficial Jets Communications Department depth chart shows two EDGE lanes. Kingsley Enagbare is followed by David Bailey in one. Joseph Ossai is followed by Will McDonald IV and Braiden McGregor in the other. McDonald is directly behind Ossai, second in that lane.
That sequence explains why McDonald’s name belongs in the immediate discussion. It does not establish a coaching hierarchy, starting assignment, replacement plan or snap order. The chart identifies where the communications department placed the players. Glenn’s actual usage still has to appear in games.
The position labels elsewhere also require a clean distinction. The NFL.com Jets roster lists McDonald and Ossai as defensive ends while listing Enagbare and Bailey as linebackers. Those identity labels are different from the EDGE lanes on the Jets chart. Their listed roster status does not answer game availability or deployment.
Readers looking for adjacent roster context can also revisit the separate JetCast coverage of Kingsley Enagbare’s Jets role and David Bailey’s discipline. Those are related position-group topics, not evidence of how Glenn will divide the current EDGE work.
What the Jets Already Know About McDonald
The Jets have been direct about the shape of McDonald’s development. In the team’s official development feature on McDonald, Glenn called pass rushing his wheelhouse and identified run defense as an area for improvement. McDonald also acknowledged room to improve his run game and said he had added a couple of pounds to help that work.
That creates a clear football objective. The Jets do not need to search for McDonald’s standout skill. They need to determine how many ways they can make that skill available. If he can stay functional when an offense runs at him, changes its presentation or forces him into a broader assignment, Glenn can use the rush without limiting the defense around it.
The same Jets article describes several possibilities. McDonald can stand up at outside linebacker, put his hand down at defensive end and occasionally drop into coverage. It also describes a defense that can use both 3-4 and 4-3 structures along with five-man fronts. Those possibilities do not confirm his Week 1 assignments. They explain why development outside pure pass rush matters.
Glenn’s stated staff plan is to place McDonald where his strengths can work while continuing to develop weaker areas. The Jets can feature what McDonald does best without pretending the rest of the job has already been answered.
Why Run Defense Still Controls the Bigger Role
Run defense matters because an EDGE defender rarely gets to choose the kind of play coming at him. An offense can run toward his alignment, use motion to change the surface or make him process an assignment before he gets a clean rush opportunity. McDonald’s ability to respond affects how broadly the Jets can deploy him.
This is not solely a question of winning one matchup. Alignment rules, edge integrity, recognition and occasional coverage responsibilities can all influence whether a player remains useful as the call changes. If McDonald becomes more dependable across those tasks, his pass rush can stay on the field in more situations instead of being isolated to an obvious passing context.
The challenge is best framed as reliability, not a settled verdict on his run defense. McDonald and Glenn have both identified the area for improvement. The next step is seeing whether that work supports a more complete role. The injury in his depth-chart lane raises the value of that progress, but it does not turn progress into proof.
For broader background, JetCast’s Jets roster projection and defensive line coverage remain useful related reading. The present McDonald question still has to be answered by current usage rather than earlier roster discussion.
What Week 1 Can Actually Tell Us
Week 1 can provide the first current evidence about the role. The useful details will be situational: when McDonald enters, where he aligns, whether he appears beyond obvious passing downs and what responsibilities accompany his rush opportunities. Those observations can show the range of work the Jets are prepared to give him at the start.
One game will still be a limited sample of the plan. Opponent, game state and specific calls can shape usage, while Ossai’s week-to-week status adds another variable. The important point is to observe what McDonald is asked to do, not to reverse-engineer a season-long hierarchy from one snap pattern.
If the Jets use him across alignments and situations, that would offer an early indication that his broader development is supporting the pass rush. If his work is more specialized, it would describe the opening plan rather than permanently define him. Neither outcome would prove a promotion, a demotion or a final answer.
Ossai’s injury has made the Will McDonald question harder to postpone. The depth chart connects the two players in one EDGE lane, and McDonald’s pass-rush strength gives the Jets an obvious tool to explore. How often they can use it will depend on more than the rush itself. Week 1 is the first chance to see how the Jets balance that strength with the reliability the larger role requires.
