INDIANAPOLIS (AP) — Justin Smith had 20 points and played a key role in a final-play defensive stop, helping Arkansas beat Texas Tech 68-66 in the NCAA Tournament. That secured the program’s first trip to the Sweet 16 in a quarter-century. In the final seconds of a tense finish, Smith found himself defending Kyler Edwards beyond the 3-point arc. Edwards drove into the paint with Smith on his hip and missed a layup, with Arkansas grabbing the rebound and running out the clock. Terrence Shannon Jr. scored 20 points for the sixth-seeded Red Raiders.
