Chiefs’ rookie shares major update on injury concerns

The Chiefs have not given a specific date for Delane to return to full contact. The exact nature of the shoulder injury remains genuinely undisclosed. Neither the Chiefs nor Delane have identified it.

Delane is expected to compete for a starting job after a college career with 41 passes defended and eight interceptions in 44 games.

“Oh, yeah, that’s something that’s going to be hard for me to turn down my aggression, but, you know, obviously, you got to be smart. It’s the NFL. You know, you got to protect your teammates. That’s the most important thing,” Delane said, as per KSHB41 shared via YouTube.

Delane used his time away from full practice to study the playbook and maintain his conditioning. Head coach Andy Reid said on Friday that the rookie was going through his final physical and doing well, while Delane’s return the following day gave Kansas City another positive sign.

Delane’s progress gives the Chiefs one less worry at the start of camp, but other young defenders are entering a different test as the pace and competition begin to rise.

Delane’s progress masks bigger rookie challenges

Kansas City’s rookies got their first real taste of training camp Saturday in St. Joseph, with veterans scheduled to join them Tuesday. For defensive linemen Peter Woods and R Mason Thomas, that means the early learning period is about to become much tougher.

Both rookies pointed to technique, footwork, and knowing the playbook as keys to handling that jump.

“I think technique outweighs the weight room,” Thomas said in the same conference. “Technique kind of saves you when you might not be the ideal weight.”

Thomas stands 6-foot-2 and weighs 249 pounds, so he knows he cannot rely on size alone. Thomas had 6.5 sacks and 19 solo tackles for Oklahoma in 2025. Now, the Chiefs want to see if he can bring that same energy to the NFL.

Kansas City has not added a veteran edge rusher, which could open the door for Thomas and second-year defender Ashton Gillotte to earn more snaps. Peter Woods, the No. 29 pick, will get his own chance inside as the Chiefs look for more help next to Chris Jones.
