Day 6 of training camp brought the kind of news the San Francisco 49ers could not afford. Mikail Kamara, the undrafted rookie defensive end, suffered a knee injury and was carted off during practice, and that is another ugly reminder of just how fragile this edge group already was.
This was not some isolated scare in a healthy room. The 49ers entered the day without full participation from their two starters, with Nick Bosa only taking part in team drills at the start of camp and Mykel Williams on the PUP list after his ACL tear in Week 9 of last season. By the time Kamara went down, the margin for error had all but disappeared.
A depth chart under strain
In the 11-on-11 portion of practice, the 49ers were down to Sam Okuayinonu and KJ Henry to man the edges. That is not a luxury situation. That is survival mode. It underlines how quickly injuries at defensive end can turn a training-camp rotation into a near-emergency, especially when several players are already unavailable or limited.
The bigger concern is not just that Kamara got hurt. It is what his injury says about the state of the room around him. Training camp is supposed to be the place where depth gets built, where young players get chances and coaches learn who can be trusted. Instead, the 49ers are already having to patch together reps and hope the next injury does not arrive before the first problem is solved.
Kamara’s injury may not define the season, but it does sharpen the question facing San Francisco right now: how many more blows can this defensive end group take before practice itself becomes the test it cannot pass?
