Larry Johnson's appeal of his suspension by the Kansas City Chiefs will be filed on Friday, his agent, Peter Schaffer, told ESPN NFL Insider Adam Schefter.

The hearing on the suspension, which followed Johnson criticizing coach Todd Haley on Twitter and twice using a gay slur -- once in a Twitter posting and again with reporters -- is expected to be held by Tuesday.

Meanwhile, the two sides are continuing to talk to see if they can find a way to bridge any differences to avoid the hearing.
