FAYETTEVILLE -- The Big 12/SEC Challenge got more challenging for the University of Arkansas basketball team about 10:30 a.m. Saturday before the Razorbacks played TCU.
That's when Arkansas Coach Eric Musselman determined during the team's shoot-around that sophomore guard Isaiah Joe -- who had started every game for the Razorbacks the past two seasons and is averaging 16.8 points with an SEC-high 67 three-point baskets -- wouldn't play because of a knee injury.
Arkansas was coming off back-to-back losses to Kentucky and Mississippi State and already lacked depth that became thinner going against TCU, which beat No.
