Defensive back Mel Blount, who has not yet reported to the Pittsburgh Steelers' training camp at Latrobe Pa., said yesterday he will file grievance against the club this week.

Blount, who has three years plus as option year left on his contract, has demanded to be traded but the Steelers have refused to answer inquiries of other teams conerning Blount. Blount's grievance, which has been verbally expressed and will be filed in written form within days, protests the Steelers' refusal to seek a trade.

Blount filed a $5 million suit in New Orleans against coach Chuck Noll shortly after Noll, in testimony during the George Atkinson trial was compelled to admit that Blount accompanied Atkinson in what the coach once described as the NFL's "criminal element."

Prior to the Atkinson trial. Blount had decided not to attend camp unless his reported $50,000 per year contract was renegotiated.

The Steelers will have 10 days to respond to the grievance before it goes to the Player Relations Committee, comprised of Oakland Raider Gene Upshaw. Washington Redskin Len Hauss, New York Giants president Wellington Mara and Steelers president Dan Rooney.

The committee must meet within two weeks of the club's refusal to comply with the grievance and if it is unable to decide the matter within five days, the case goes to an outside arbitrator.

Blount, working at his farm in Vidalis, Ga., reaffirmed that he will nevery play for the Steelers again.

A Steelers spokesmen said. "He has a contract and we expect him to honor it. We want him to play for Pittsburgh.
