The former Chicago Bull reportedly suffered a meniscus tear in his left knee recently, and after surgery will be out for six weeks, according to a tweet from Howard Beck of the New York Times.
Considering that Brewer himself was brought to New York to cover for the injured Iman Shumpert, this is terrible news for the Knicks, as they lose a player who would likely have started for them until January.
All is not lost for Brewer, though, as opening day doesn't come for another eight weeks, meaning that he could be back in time if the reported time scale is correct.
That said, knee injuries are not to be taken lightly, especially for basketball players, so keeping Brewer out of action until it's completely safe to play him—even if that means missing opening day—could be in the Knicks' plans.
At the very least, a huge chunk of the preseason will be missed by Brewer, which could leave him struggling to catch up and build chemistry once he finally gets back on the court.
The best-case scenario would have Brewer back with a few preseason games to spare, but this injury could still lead the Knicks to make another signing just to shore up their depth on the wing.
Rumors of a possible move for former All-Star Josh Howard have come to fore recently, and we may see an advancement in negotiations there if the Knicks feel they need an extra swingman.
Howard is perfectly capable of playing the 2, and he would be a fine player to start for a few games if need be.
Thankfully, the situation could be a lot worse than it is for Brewer and the Knicks, and if all goes well, this shouldn't have much of an impact on the season. But don't be the surprised if this triggers Glen Grunwald's 10th new signing of the offseason.
