NFL Media Insider Ian Rapoport reported that Orton was not at the team facility Tuesday after failing to show for a Monday physical as he strongly considers retirement.
"It's definitely a breath of fresh air," Weeden said of his time with the Cowboys. "I'm excited to be here. I love coming to work every day. It's a fun environment."
Weeden sports a strong arm, but his decision-making too often veered into mind-boggling territories in Cleveland, leading to his 26 interceptions over 20 starts.
Now learning his third offense in as many seasons, Weeden has yet to prove he can capably direct an NFL offense. With nobody else applying for the job, the Cowboys are giving him what could be his last chance at this level.
