However, Troy didn't roll over after getting down 31-7 and Ronnie Wingo decided he wasn't ready to give up his starting spot just yet.
"The positives were the way we started the game," Arkansas head coach Bobby Petrino said. "We came out of the locker room and started fast. We executed well on offense, moved the ball down and scored. I was really encouraged with the way Ronnie Wingo was running the ball and our offensive line blocking the run game.
"Defensively, they did a good job of executing their passing game as they always do," Petrino added. "They always get the ball out of their hand quick. They have guys that can make plays after the catch. I think we were in position about three or four times to play the deep ball and we didn't get it done. We didn't have confidence to turn and look for the ball and they made good plays."
Wingo's previous career highs were 12 carries last week and 84 yards against Texas A&M two seasons ago.
He and the other tailbacks have taken some criticism from their own fans and that has clearly resonated with him.
"It's a relief after everybody was on our back the way they were the first week," Wingo said. "They are still going to have stuff to say, but we have got to keep grinding and getting better each day."
Joe Adams also had an eventful night for Arkansas (3-0) with 8 catches for 109 yards and a touchdown and 3 carries for 18 yards rushing – but also two fumbles.
He made it six straight games that Arkansas has had a receiver with over 100 yards and had a 56-yard touchdown catch after the Trojans (0-2) had cut the lead to 10 in the third quarter.
"I thought it (the TD catch) was a huge play for us," Petrino said. "He made a great play. They tightened the score. We hadn't move the ball real well the last two drives and Joe made a great play. He broke a tackle, showed his speed and changed the game back for us."
Tyler Wilson was 23-of-36 passing for 301 yards, but also had one of his passes picked off and taken back for a touchdown.
He also drew the wrath of Petrino for some passes that sailed over the heads of open receivers.
"It was a combination of several things," Petrino said. "Our timing in the passing game was off. I thought he (Wilson) might have been looking at the rush. They were blitzing us a lot. There was a stretch where they blitzed nine (times) in a row."
It was the Razorbacks' final tune-up before Alabama (3-0), who beat North Texas 41-0 on Saturday night, and was the first time they have started 3-0 in consecutive years since 1988-89.
Arkansas and Alabama will meet next Saturday at 2:30 in a game that will be nationally by CBS.
"I wasn't real happy with the way we finished the game," Petrino said. "We have got a lot to work on before we play Alabama."
He added "we could be better on third downs (8 of 16) and we have a lot of things to work on."
The Razorbacks played without three key starters – defensive end Jake Bequette (hamstring) and wide receivers Jarius Wright (strained knee) and Greg Childs (grandmother's death).
Wright and Childs are slated to play against the Crimson Tide while Bequette will likely be a game-time decision.
Troy lived up to its reputation as a high-powered offense as quarterback Corey Robinson was 36-of-63 passing for 373 yards and the Trojans had a 457-454 total offense advantage.
"Their quarterback had a quick release," noted Arkansas defensive tackle D.D. Jones, who lined up some at defensive end with Bequette out. "He was getting the ball out of his hands so fast that it was hard for us to get to him, but we did everything we could to come out with a win and that's what we did."
Johnson did get some action, his first since a season-ending bowel injury back in September of last season.
He had 4 carries for 22 yards and returned 2 kickoffs for 54 yards.
The night certainly began like the Razorbacks were going to blow out a third straight foe.
Arkansas' offense scored on its first four possessions with Wingo racing in from 22 and 21 yards out, Kody Walker bulling in from 3 yards and Zach Hocker drilling a 22-yard field goal for a 24-0 lead with 6:01 left in the first half.
"I think Arkansas has got to be one of the best offensive teams in the country once you get right down to it," Troy head coach Larry Blakeney said. "They've got a lot of guys that can make a lot of plays. I felt like we were slow getting lined up, not quite on edge as much early and we gave up some plays that we shouldn't give up.
"They've got some skill guys that can really play," Blakeney added. "Their quarterback is a really good player. They hit us with some power formations and big plays. They know what they are doing and they are certainly a very good football team."
But Troy did not go away and cut it to 24-7 right with 7 seconds left before halftime when Eric Thomas caught a 3-yard pass from Robinson.
Arkansas scored on its first possession of the third quarter, going 79 yards and capping the 11-play jaunt with a 6-yard scoring toss from Wilson to Wingo.
Hocker's PAT made it 31-7 before Troy got back into it in quick fashion.
Robinson hit Justin Albert on a 32-yard touchdown pass and then 28 seconds later LaDarius Madden picked off Wilson and returned the pick 53 yards for a score.
In a span of 28 seconds, it went from 31-7 to 31-21 with 6:12 left in the third quarter.
Asked what happened, Petrino said "I wish I knew."
Adams – as he has been doing all season – then electrified the crowd by catching a short pass, spinning away from a tackling and racing the rest of the 56 yards for a touchdown.
That play grabbed the momentum back for Arkansas, which went out 38-21 with Hocker's PAT with 14:09 left in the contest.
"They made a good play," Madden said. "He's a heck of a football player. He just made a play at that point in time and then after we just could never get it back together."
Arkansas appeared ready to throw the knockout punch when it stopped Troy deep in its own territory, but Adams fumbled the punt near midfield.
Troy capped the scoring with 28 seconds left when Robinson hit Thomas again – this time with a 24-yard TD pass.
"I think in the second half that we stayed on the field too long, but we'll get everything settled before Alabama," Jones said.
