Free agent TE Dustin Keller left his Wednesday Patriots visit without a contract. A source (Keller's agent?) told the Boston Herald that Keller's "knee is healed." It looks like the Patriots were not convinced. Just eight months removed from tearing three ligaments and dislocating his knee, it's not a surprise. If Keller can eventually prove his health, the Patriots would make for an excellent landing spot as they're desperate for a "move" tight end. The three tight ends currently on their roster are Rob Gronkowski (ACL), Michael Hoomanawanui and D.J. Williams.
