The Kansas City Chiefs were negotiating a trade for Seattle Seahawks safety Earl Thomas before he suffered a season-ending leg injury in Sunday's 20-17 win over the Arizona Cardinals, Yahoo Sports' Terez Paylor reported Monday.
"The Chiefs, in particular, were particularly annoyed with the development, as sources tell Yahoo Sports that although the two teams couldn’t agree on a trade this past week, the two sides were inching closer toward a deal and there was internal optimism something would be struck before the deadline," Paylor wrote.
According to NFL Network's Ian Rapoport, Thomas suffered a "clean, lower leg break" that will rule him out for the rest of the regular season.
