The move may become official during Cowboys coach Bill Parcells' news conference at 11:30 a.m. PT Wednesday at the team's training camp headquarters in Oxnard, Ca.
According to an earlier broadcast report, Carter was AWOL from practice Wednesday morning, and the absence is not injury related and the Cowboys will be making an "official" statement regarding Carter after the conclusion of practice. But other broadcast reports have intimated that the Cowboys quarterback will be released, leaving Vinny Testaverde and Drew Henson to battle for the starting position.
Micky Spagnola, the station's Cowboys beat reporter, compared the situation to that of Tony Banks three years ago where Banks was absent from practice and it was announced after practice that he had been cut.
This move comes on the heels of unanimous opinions that Henson has been the best quarterback in camp thus far, which had to be at least mildly upseting to Carter, who started all 16 games for the Cowboys in 2003, leading them to a 10-6 record.
In his first season as the full-time starter - after splitting time the first two seasons - Carter threw for 3,302 yards, but had 21 interceptions and 17 touchdowns. He was intercepted at least twice in six games.
