The Vikings designated Cashman (hamstring) from return from the injured reserve Monday.
The veteran linebacker has missed Minnesota's last four games after being placed on IR following Week 1 due to a hamstring injury. After a Week 6 bye, Cashman is ready to practice again, and the Vikings will now have 21 days to evaluate him before he'll need to be added back to the 53-man roster or remain on IR for the rest of the season. Once Cashman returns to full health, he's expected to slot back into a starting role at linebacker.
