08:08 AM ET 10.18 | Thankfully, not all injuries are alike. Last preseason: Blake Griffin injured. This preseason: Griffin injured. That's where the similarities end. Just in case Griffin's ankle injury and absence from Sunday's exhibition game seem alarming for Clippers fans, it should be remembered, of course, that not all injuries are created equal. With Griffin's knee injury last season, it became fairly clear within a day that it was a serious one and ended up season-ending. This injury, a sprained left ankle, was more of a tweak, and Clippers Coach Vinny Del Negro said it was not serious. He thought Griffin would try to practice Monday and would play Tuesday.
