The 49ers have announced that they have promote CB Tramaine Brock from the practice squad to the 53-man roster, and waived LB Diyral Briggs to make room for Brock. I'd imagine this move comes in light of the need for cornerback depth against a strong New Orleans Saints passing attack. Throw in the fact that CB Will James is doubtful and CB Phillip Adams is questionable for tonight's game and this is not a surprising move.
Obviously some folks will be broken up over the waiving of Diyral Briggs. It will be interesting to see whether he clears waivers in the coming days and potentially ends up back on the practice squad. Or this could be a short term move for this week with the team attempting to bring back Briggs once they get healthy. We'll keep an eye on this going forward.
