Yes, it should safe to eat. Make sure you smell it, that's often the best way to detect if it's gone bad. Depending on the size of the leg, and the temperature of your fridge, it's not unusual for a large piece of meat to take that long to thaw. Once cooked, it should last for 3 or 4 days. It will start tasting a little gamish before it actually goes bad. Removing the meat from the bone after 1 or 2 days helps making it last a wee bit longer. Enjoy!
