Chiefs Thursday injury report: Questions surrounding Breeland Speaks emerge

The Kansas City Chiefs had some good news and some bad news when it came to injuries on Thursday. Let’s start with the good news.

After participating only partially on Tuesday and Wednesday, safety Tyrann Mathieu was back to full practice Thursday, even recording a one-handed interception for the second day in a row.

“He was full-go [Thursday] and did his thing and worked [Wednesday],” Chiefs head coach Andy Reid said. “He banged up his shoulder just a little bit—I’m being a little bit cautious with that, get him ready for the season. We’ll see about Saturday night (against the San Francisco 49ers). He might be a guy that we end up sitting down Saturday night, and we go from there.”

And now for the bad news—five Chiefs missed Thursday’s workout headed into the game, highlighted by defensive lineman Breeland Speaks, who continues to deal with a knee issue following last Saturday’s game against the Pittsburgh Steelers.

“I’m having him meet with some doctors here and just checking that thing out and letting it calm down and see where we’re at,” said Reid, who was asked if there is swelling in Speaks’ knee. “Some of it’s the swelling. I can’t tell you the whole thing, because I’m a coach.”

The news means Speaks won’t go on Saturday. And based upon Reid and the Chiefs’ history, neither will wide receiver Gehrig Dieter, defensive back Michael Hunter, H-back John Lovett nor tight end Deon Yelder.

The Chiefs play the 49ers at 7 p.m. Arrowhead Time.
