Dallas Cowboys owner and general manager Jerry Jones says heads aren't going to roll as a result of Sunday's loss to the Detroit Lions. The visiting Lions destroyed the Cowboys 47-9, handing Dallas its worst home loss since 1988. When reporters asked whether head coach Mike McCarthy's job is in jeopardy, Jones said he's "not considering that." Jones said the team will use the bye week to look things over. The Cowboys will take on the San Francisco 49ers in Week 8.
