Michael Vick was a no-show at his celebrity golf tournament Sunday after probation officials restricted travel for the Eagles quarterback this weekend.

Vick spokeswoman Judy Smith said that Vick's travel has been at the discretion of his probation officer since he was released from prison in a federal dogfighting case in May 2009.

Vick missed the Michael Vick Celebrity Golf tournament in Georgia and also did not make a scheduled appearance at a youth football camp in Raleigh, N.C., this weekend, much to the director's ire, who said Vick cancelled at 2 a.m.

•The future of testing for human growth hormone is shaping up to be a contentious issue in negotiations between the NFL and the players' union.

NFL Players Association President Kevin Mawae told the Associated Press the union is aware of developing tests, one of which is a blood test that could detect HGH for up to 14 days.

But he also said the union believes the test that is currently available, which has only about a 48-hour window of detection, "is not completely reliable."
