From the Niner Insider:

ALLEN TO COWBOYS?: I just got an e-mail to from a league source saying that former 49ers guard Larry Allen is about to sign in Dallas. Interesting.

Another NFL source said he might be signing just to retire as a Cowboy.

Hard to believe, cuz I was just wondering about his availability.  Then I quickly dimissed the thought as I thought it was too far-fetched.

What do you guys think?
