"It's a dead issue. A dead issue," Jones told USA TODAY's Nancy Armour.
Armour also conducted an informal poll of Cowboys fans at Sunday's game against the Giants. Seven of the 15 fans she questioned did not know Sam was on the team's practice squad.
Sam was the named Co-Defensive Player of the Year in the SEC last season after recording 11.5 sacks for the Missouri Tigers.
He was taken in the seventh round of this year's draft by the Rams and had three sacks during the preseason. The Rams released him at the end of training camp, and chose not to sign him to their practice squad.
