The Detroit Lions have made a trade. Quarterback Thaddeus Lewis has been sent to the Buffalo Bills, according to Pro Football Talk. It's not currently known what the Lions are getting in return for Lewis, but I'd imagine it's just a seventh-round draft pick (possibly one of the conditional variety) unless the Bills gave up a wide receiver.
Lewis joined the Lions this offseason after being claimed off waivers from the Cleveland Browns. He went into training camp hoping to beat out Kellen Moore for the third spot at quarterback, but that didn't end up happening. Lewis played pretty well in the preseason, going 6-for-8 for 60 yards, but Moore solidified his spot on the depth chart with a stellar performance against the New England Patriots.
In other words, Lewis was going to be released in the next week by the Lions anyway, but the suddenly quarterback-needy Bills decided to trade for him in order to ensure he ended up in Buffalo. With Kevin Kolb and E.J. Manuel currently injured, the Bills already added Matt Leinart earlier on Sunday, and now they've got Lewis as well.
Given the quarterback situation for the Bills, we could see Lewis play on Thursday when Buffalo hosts the Lions in their final game of the preseason. In fact, we could get a Moore/Lewis matchup for a good portion of Thursday's game.
