Merriman, the defensive rookie of the year in 2005, said the positive test was the result of a tainted supplement. He practice with the team on Monday, one day after the Chargers suffered a 30-27 defeat in Kansas City.
"I will try to deal with it accordingly," Merriman said. "I hope nobody makes any kind of judgment or anything that makes me guilty of anything because nothing has been done wrong on my part.
"I will try to get it straightened out as soon as possible without missing any time."
If his appeal is denied, Merriman would miss four games. The Chargers are already thin at the outside linebacker spot, with Steve Foley out after being shot by an off-duty police office and Shaun Phillips suffering a calf strain against Kansas City last week.
"What is important for me is to try and get back on the field and help this team win," Merriman said. "It is something that I am dealing with and I will take a lot of effort in doing the right thing, and I will continue to do the right thing.
"No matter what happens I will be taking responsibility. I am not running from the situation here; I will do what is best for this organization and this team."
"I have no reason to do anything wrong especially when I am already in the spotlight. This obviously is a mistake that has to be dealt with and hopefully no judgment is made about me before everything comes out. Believe me, when I am able to speak on these things, I will."
Chiefs planned for Johnson/Gonzalez
This was getting back on the horse. It was standing up the eighth time. It was a whole bunch of Herm Edwards analogies wrapped into one.
He called himself a preacher. He called the Oct. 15 loss against the Steelers a club fight the Chiefs attended without a club.
In the end, he said, Sunday's win over the Chargers was about character.
"We were tested this week," he said, "to find out what we were about."
The Chiefs found out their offense could still produce as it did in the old days, and do it against the NFL's No. 1 defense. The 355 yards were a season high and they came about -- here's a light bulb moment -- by giving their best players the ball. Larry Johnson rushed for 132 on 28 carries, and Tony Gonzalez converted his six grabs into 138 yards.
Both players came up huge on the Chiefs' final drive, with Johnson gaining the first 15 yards after shaking three tackles and Gonzalez getting the next 37 on two catches.
"I told (Gonzalez) and Larry that we were going to get them the ball this week," Edwards said. "(Gonzalez) made some big-time catches, but what he did also was make some big-time runs after the catch -- he and Larry both."
It was the first time this season the Chiefs had a 100-yard rusher and a 100-yard receiver in the same game.
