How long should i cook a frozen roast?

[jmklovesaner]

I just put a frozen roast in the crock-pot on high. Im having company and later this evening and completely forgot to put it on last night. The roast is a little under 2 lbs. How long should i let it cook?

7-9 hrs on low but i would start with high for the first 2 hrs
