Rookie minicamps dont allow practices in full equipment or pitting players against each other in contact. They do allow evaluations, however, of undrafted free agents and tryout players with a purpose in mind.

Were trying to find a ruby, said offensive coordinator Mike Tice. If we can find ourselves a ruby -- someone we can polish up and turn into a nice shiny stone -- that wouldnt be a bad thing either.

The Bears found seven possible rubies in the form of players in for a tryout and they signed those on Sunday, including a guard, tackle and tight end. To create roster space, three former ruby hopefuls were waived on Monday: tackle Levi Horn, tight end Andre Smith and guard Reggie Stephens.
