Chiefs Tuesday injury report: Six Chiefs held out of practice

The Kansas City Chiefs were back at their usual facility in Kansas City on Tuesday for their first practice following training camp.

The Chiefs waived wide receiver Davon Grayson (knee) during practice, bringing back former Chief De’Anthony Thomas in his place. Wide receiver Marcus Kemp was moved to injured reserve after tearing his ACL and MCL.

There is no progress to report when it comes to Gehrig Dieter, Michael Hunter or John Lovett. All three players missed the preseason game against the Pittsburgh Steelers. Deon Yelder, who injured his knee in the game, did not practice.

Chiefs head coach Andy Reid said the Breeland Speaks’ knee is still being evaluated after he hurt it in Saturday night’s preseason game. Assessing Reid’s post-game comments, our in-house injury expert Aaron Borgmann suggested the injury could be a hyperextension, and the team is being cautious.

Safety Tyrann Mathieu only lasted two plays in the game against the Steelers before injuring his shoulder, and Reid said in a conference call Sunday that Mathieu would have likely stayed in the game had it been the regular season. Mathieu participated in individuals on Tuesday but did not partake in 11-on-11 drills.

The Chiefs will continue their preparations to face the San Francisco 49ers when they resume practice at 1:40 p.m. Arrowhead Time on Wednesday. Coordinators Eric Bieniemy and Steve Spagnuolo are scheduled to speak to the media around 10:30 a.m.
