For experienced QB depth, Pats pluck Lemon

Posted by ESPN.com's Tim Graham Lemon
The New England Patriots clearly aren't satisfied with their quarterback depth behind Tom Brady.

An NFL source tells me the Patriots are on the verge of signing journeyman Cleo Lemon to be Brady's top backup. Lemon tried out for them Friday afternoon in Foxborough, Mass. The signing is expected as early as Saturday.

Bill Belichick must crave additional experience at quarterback. New England's depth chart includes Kevin O'Connell (third-round pick last year), Matt Gutierrez (undrafted third-year pro) and Brian Hoyer (undrafted rookie).

O'Connell has six NFL attempts. Gutierrez has five.

Lemon has played in 16 NFL games for the San Diego Chargers, Miami Dolphins and Jacksonville Jaguars. He hasn't completed a pass since 2007, when he started seven games for the 1-15 Dolphins.

Lemon spent last year with the Jacksonville Jaguars and served as David Garrard's backup. In June, the Jaguars terminated his contract with two years remaining.
