Adam Schefter of the NFL Network reports that the Cowboys have used the franchise tag on S Ken Hamlin

The Pro Bowler finished last season with 62 tackles and five interceptions. He will make $4.3 million in 2008, and it's the first time the Cowboys have used the franchise tag since placing it on LT FLozell Adams in 2002. Ironically, putting the tag on Hamlin means that Adams will likely become an unrestricted free agent next week.
