Henry had started Arkansas' previous two games and had scored in double figures in its previous three contests. But Henry missed some practice time because of his sore right knee in advance of Arkansas' 75-62 loss at Auburn, forcing Pelphrey to make a change.
"Jason's had a tough time the last couple of days with his knee," Pelphrey said. "He couldn't really practice, and I don't even know how many shots he's been able to get up (since Saturday's game at Mississippi State)."
Sanchez "stepped in there and competed well," Pelphrey said, finishing with nine points and six rebounds in 25 minutes of action. Henry did enter the game at the 7:11 mark of the first half, but he never appeared comfortable and scored only two points in nine minutes.
Freshmen Brandon Moore and Andre Clark also helped out in the frontcourt, subbing for Henry, Sanchez and junior Michael Washington, who was whistled for two early fouls. Moore had four points, five rebounds and two blocks in 17 minutes, while Clark added two points in nine minutes.
Arkansas freshman point guard Courtney Fortson had his own cheering section Wednesday night in Beard-Eaves-Memorial Coliseum.
About 15 of his friends and family, his mother Lorraine included, traveled 45 miles from Fortson's hometown of Montgomery.
"That was great, but we didn't get the victory, so I haven't really thought about it," Fortson said after scoring 11 points, grabbing seven rebounds and dishing out five assists.
Most of that production came in the first half, but Fortson battled foul trouble after halftime. He picked up his fourth foul at the 8:29 mark, sat until the 5:07 mark and earned his fifth foul just 44 seconds after returning.
Fortson was angry about the touch-foul call on a drive by Auburn's DeWayne Reed, voiced his frustration on his way off the floor and was called for a technical foul.
The Tigers hit 3 of 4 free throws to go up 67-60 with 4:23 left.
"I was asking for an explanation really," Fortson said.
• Senior forward Marcus Monk missed his sixth straight game because of eligibility issues. He didn't travel to Auburn, the second straight road trip Monk missed.
• The first of Fortson's fouls was an intentional foul only 18 seconds into the game. Fortson shoved Auburn's Rasheem Barrett after Sanchez opened the scoring.
• Arkansas fell to 0-5 on the road in SEC play this season, clinching its 14th consecutive season with a losing road record during league play.
The Razorbacks play a pair of home games over the next week, beginning with Saturday's contest against Kentucky in Bud Walton Arena. The 12:05 p.m. game will be televised by CBS.
Arkansas takes on LSU at 7:05 p.m. on Feb. 18.
