  We interpret the recent ATLAS multi-jet search results using 20.3 fb-1 data
at sqrt(s)=8 TeV in the context of searching for excited quarks. Within the
effective field theory framework, using the null results of that search, our
analysis shows that the excited quark mass below 5 TeV can be excluded at the
95% confidence level. Our analysis also indicates that when the validation of
effective field theory is considered, the limit can be largely compromised.
