This analysis presents first preliminary results on jet shapes and energy flows in inclusive dijet production based on $\sim 77 \ {\rm pb}^{-1}$ of RUN II data. Jets are searched for using a cone algorithm with radius $R=0.7$. Jet shapes are determined using both calorimeter towers and tracks from the COT. The measurements are compared to leading-order QCD Monte Carlo predictions.
