Claiborne, the No. 6 overall pick in 2012, allowed five receptions for 108 yards Sunday against the Rams, who started Austin Davis at quarterback.
The disgruntled defender reportedly skipped the Cowboys’ walkthrough practice on Tuesday.
Despite the demotion, coach Jason Garrett and owner Jerry Jones have been at least superficially supportive of Claiborne. His track record and the elevation of Scandrick might say otherwise.
