In what you might call a surprise move, the Steelers have waived John Malecki in order to sign C/G Cody Wallace. Wallace has spent time on various practice squads over the past few years, and was just waived by Tampa Bay during their final roster cuts. Wallace is 6-4, 300 lbs.
Wallace drew somewhat sporadic grades from ProFootballFocus during the preseason. He scored well in run blocking during some games, and poorly in others. He is a four year veteran.
