With the Atlanta Falcons struggling again this season after reaching the NFC Championship Game in the 2012 season, the status of Mike Smith as head coach is uncertain.

The Falcons are on a five-game losing streak.

"No," Smith said about if he's concerned about his job security. "None whatsoever. We're going to do what we've done for the last six-plus years and prepare each and every week like we know how to do it. And I'm going to continue to do that until Mr. Blank tells me otherwise."

Arthur Blank recently told ESPN.com he had confidence in both Smith and general manager Thomas Dimitroff to guide a turnaround and said he would wait to see how the season plays out before evaluating changes. But Blank was noticeably frustrated after Sunday's loss in London, telling the Atlanta Journal-Constitution: "There's no way you lose that game -- just no way. There's nothing else I can say."
