When Dexter McCluster finished practice last Wednesday, he noticed that something was wrong with his ankle. He knew he’d gotten a small cut there a few days earlier, in the Chiefs’ 45-10 win over Washington, and he also knew it was way more swollen than it should have been.

But when he went to the Chiefs’ medical staff and later found out the cut had been infected and needed to be cleaned out and treated with antibiotics, well, he hadn’t expected to hear that.

“I just thought, wow, something that small, a cut that I get every day in this sport (did that),” McCluster said. “I took it very seriously. I wanted to make sure it didn’t move and it didn’t spread, that it didn’t infect my body as a whole.”

McCluster had a little help understanding the seriousness of the situation. Once he found out the news, he decided to call his mom, Wendy, a certified nursing assistant who promptly started doing mom things.

“I’ve got to call her and let her know what’s going on in my life, you know, (because) she worries,” McCluster said.

Wendy promptly threw out the names of possible causes, including MRSA, a nasty antibiotic-resistant staph infection that has affected at least three members of the Tampa Bay Buccaneers this season.

Surprisingly, McCluster had never heard of it.

“I’m like ‘Mom, I don’t know what that is,’ ” McCluster said with a laugh. “‘But I hope it’s not.’”

Fortunately for McCluster, it wasn’t. McCluster’s tests came up negative for the infection, and though he missed the Chiefs’ 56-31 rout over Oakland on Sunday, that set the stage for him to return this week. “That’s the plan,” Chiefs special-teams coach Dave Toub said. “We cut Chad (Hall) (Thursday), and that’s an indicator that we think Dexter is going to be OK for the game.”

Hall — who was re-signed late last week when it was obvious McCluster’s availability for the Oakland game was in doubt — had only one return in the win over the Raiders.
