Sometimes, though, teams have so many injuries (or fake injuries, whatever) that they can't all be fit on the list, therefore someone has to wait for another person to come back before they can go on the injured list. Jamaal Tinsley has had foot problems for like a month and a half, but they kept him off thinking he could go, then Jermaine went down and they couldn't put him on the list when they wanted to. Some of the injuries are also made up by the team just to get them on the list, because they have 15 on the roster but can only use 12, and the extra three have to go on the list. Jamison Brewer, for example, has spent virtually his entire career on the injured list (not sure how much he's played this year though, for the Knicks).
