It appears Kansas City Chiefs defensive end Frank Clark might have to endure another “flu game” down the line.

Andy Reid announced on Wednesday that Clark would undergo tests with a specialist to find out more about his stomach issues, which seem to extend beyond the normal flu bug. It was the topic during Reid’s opening statement at his press conference and extended a few questions beyond it.

“As far as the injuries go, Frank Clark is going to see a specialist – his stomach is still bothering him,” Reid began. “I feel bad for him. We just have to get it answered. We’re looking into that.”

As for what Week 14 and Sunday looked like for Clark, it was clear that he gutted through a lot to play. At the same time, the only reason he was able to play was because of how the illness had subsided ahead of the game and how the team managed his snap count. Now, things seem to have backtracked for Clark.

“You’re dealing with a guy that loves to play,” Reid said of Clark. “I think we know that. There’s nobody that loves to play more than him. We were managing it and making sure that he was OK to play. Then, it kind of subsided a bit. Then, it has reoccurred today. We’ve been in contact with a specialist, and he’ll see that specialist. We just want to make sure that he is OK. We’ll just see from there where it goes.”

Now it’s just a question of what Clark is dealing with and whether he’ll be good to play in the immediate future. It could be a stomach virus or it could be something entirely different.

“Not sure. I think that was probably the initial thought. Not too many people are smarter than ,” Reid said. “ visited with some other doctors. But we found somebody that he can go see that might be able to get a grasp on this thing and see exactly what it is. That’s kind of where we’re at. Just kind of waiting and trying to get him as comfortable as possible.”
