This pretty much solidifies what we've all been speculating. Via Josh Looney:
The Chiefs are currently going through final preparations for the Redskins this Sunday at FedEx Field. For the third consecutive practice, LT Branden Albert (ankle) was off to the side on stationary bikes. Utility OL Wade Smith continued to get first-team reps at left tackle, while Barry Richardson (of the practice squad backed him up). The Chiefs other tackle, Ikechuku Ndukwe, was running with the second team at right tackle during the early portion of practice.
Some good news, however, was the return of Jarrad Page to the practice field. Page has been nursing a sore shoulder.
We'll update this with more info as it come in. Albert will not play on Sunday against the Redskins.
