Charlie Wysocki, a former University of Maryland tailback, was the only one of 98 players signed by the Washington Federals who failed to appear for equipment fitting and physical examinations today as the team assembled to begin the U.S. Football League's first season.

Practice officially begins Tuesday at 2 p.m.

Wysocki told General Manager Dick Myers about two weeks ago that personal problems might prevent him from playing. "At this time, we just don't know about Charlie for this year," Myers said. "We have not written Charlie completely out of our plans. If it doesn't work out that he's ready to play this year, we will certainly give him an opportunity next year if he so desires."

Wysocki was placed on the reserve list, which means he is still team property but is not on the active roster.

The Federals signed Reggie (Gnat) Smith, former Atlanta Falcons punt and kick returner, today. The 5-foot-4 Smith was fifth in the NFC in punt returns in his 1980 rookie season, averaging 9.7 yards. He was the Falcons' leading kickoff returner in 1981, returning 47 for a 24.3 average.

Smith, 26, from North Carolina Central, played the 1982 season with the Charlotte Storm of the American Football Association.

Top draft pick Craig James of SMU arrived Saturday and was one of the first today to receive his equipment and examination.

Also on hand were 11 former Redskins: defensive end Coy Bacon, punter Mike Bragg, tight end Phil DuBois, running back Bobby Hammond, defensive back Donnie Harris, wide receiver Zion McKinney, quarterback Kim McQuilken, running back Don Testerman, defensive end Dallas Hickman, tight end Reggie Haynes and running back Buddy Hardeman.

The Federals will practice through Feb. 27, then open their 18-game season March 6 at RFK Stadium against the Chicago Blitz.
