Not only has Eric Brewer had to deal with two back surgeries over the course of the last year, but he now has to contend with a knee surgery, which he has just undergone. This latest trip under the knife could cost Brewer upwards of four weeks on the shelf. It was already unclear as to whether or not he'd be ready for training camp because of his back, but having to wait 2-to-4 weeks for his knee to be ready will likely cut his training camp down significantly, if not completely.
Brewer was a solid fantasy bet in his healthy days, but I'm recommending a complete avoidance of his health headaches. If you were wise, you would avoid him at your draft this Fall and wait to see what he does when he returns to the ice.
