Thanks to GM Martin Mayhew the Lions always seem to have one more roster move up their sleeve.

Friday they signed veteran CB Dre Bly to a two-year deal. Bly played four seasons with the Lions after signing as a free agent in 2003.

It will be interesting to see what the 33-year-old cornerback has left. Last season he played in all 16 games with the 49ers, but started just six.

The secondary is an issue with the Lions with only one job secure -- Louis Delmas at free safety.

Training camp, which begins on July 31, just got a little more interesting.
