Kansas City’s injury woes deepen as veteran edge Janarius Robinson and veteran defensive back Deon Bush land on injured reserve after the weekend’s 20-17 loss to Arizona. Kansas City signed rookie defensive lineman Nate Matlack to shore up the front seven, leaving the Chiefs’ depth chart in flux as they approach Friday’s upcoming preseason tilt with Seattle. GM Brett Veach now faces questions about possible signings to fill the void and prevent a longer-term hit to the defensive rotation.

Robinson’s fractured foot and Bush’s ruptured Achilles change the Chiefs’ edge and secondary rotation, respectively. Matlack’s arrival signals a move to stabilize the front while the club weighs internal options and potential veterans. With an Aug. 15 exhibition against the Seahawks on the horizon, Kansas City will push to avoid further injuries and glean meaningful evaluations from its remaining preseason snaps.

For fantasy and betting, every snap the Chiefs’ defense and rotation can muster matters. Depth is being tested, and early signs from practice and the next game will hint at who might rise into bigger roles if injuries linger into September. KC’s next preseason showdown looms as a key data point for how the depth chart might unfold in the season opener.
