Detriot Injuries: Dats and Zetty?

I had both Datsyuk and Zetty on my one year H2H team I dropped Zetty and Dats is still there on DTD. Should I pick up Zetty again and anyone have any update on Dats? Should I keep him or pick someone else up? I currently have the bye this week and start the semi final round next week. Also any suggestion on team improvement is appreciated...still wondering about ryan, hemsky, stempniak
