POSTED 3:25 p.m. EDT, September 18, 2007 FALCONS SIGN LEFTWICH Adam Schefter of NFL Network reports that the Atlanta Falcons have signed free-agent quarterback Byron Leftwich to a two-year deal. Terms are not yet available. Leftwich was abruptly dumped by the Jaguars on September 1, one day after announcing that he'd be cut or traded. The Ravens showed some interest in the seventh overall pick in the 2003 draft, but talks reportedly broke down after roughly 3.5 hours of negotiation. In Atlanta, Leftwich could find himself playing sooner rather than later. Joey Harrington has been so-so so far, and the Falcons will want to figure out whether Leftwich can be the guy before the team positions itself to land Brian Brohm of Louisville, who was mentored until last season by new Falcons coach Bobby Petrino.
