Arkansas (16-8, 4-7 Southeastern Conference) lost its third consecutive game, shot a season-low 30.6% and fell by double figures for the first time all season. The Razorbacks had been one of only nine Division I teams to avoid any double-digit defeats.
Both teams were at far less than full strength for this one.
Arkansas played a third straight game without second-leading scorer Isaiah Joe, who underwent arthroscopic surgery on his right knee in Feb. 4 because of recurring inflammation. The Razorbacks also held SEC scoring leader Mason Jones out of the starting lineup, though he sat for under three minutes before taking the floor.
Tennessee (14-10, 6-5) played a fourth consecutive game without starting guard Josiah-Jordan James, who has a groin injury. Starting forward John Fulkerson played through an illness.
The Vols did a much better job of adapting to their circumstances.
Tennessee had five players score in double figures while Arkansas went through prolonged stretches without making a basket. Jordan Bowden had 16 for Tennessee, Fulkerson 14, Yves Pons 12 and Olivier Nkamhoua 10.
Jimmy Whitt Jr. scored 19, Desi Sills had 11 and Reggie Chaney added 10 for Arkansas, which went 7 minutes, 44 seconds without a basket during one stretch in the first half. The Razorbacks followed that up by going 8:40 without a basket in the second half.
Jones scored just nine points — less than half his season average of 20.5 — and shot 1-for-10 from the field.
Midway through the first half, Arkansas had an equal number of turnovers (nine) and field-goal attempts. The Razorbacks trailed 40-23 at halftime and never cut the margin below 15 the rest of the way.
The Vols entered the night having lost four of their last five games, but they ended that slide by playing much stronger defense.
In its previous losses, Tennessee allowed Mississippi State to shoot 57.1% and allowed Kentucky to shoot 54.3%, but on Tuesday the Vols simply refused to give up any easy baskets.
Tennessee visits South Carolina on Saturday.
