Dwan Edwards visits Bills

Free-agent defensive end Dwan Edwards left his visit with the Buffalo Bills on Tuesday without a deal, which might lead to his return to the Ravens.

Edwards has made three visits during free agency and has yet to receive an offer.

"[Free agency] has been a little difficult. I'm not going to lie," Edwards said in his first comments since becoming a free agent at the beginning of this month. "I kind of new coming in some teams might have some issues with my neck."

Edwards had spinal fusion surgery after missing the 2008 season. He said he is completely healthy.

If the Bills wanted Edwards, they probably wouldn't have allowed him to leave. On the same day Edwards was in Buffalo, the Bills signed linebacker Andra Davis to a two-year contract before his free-agent visit was over.

Edwards said he doesn't have any other free-agent visits scheduled.
