Leonard was limited in the second half of the Aztecs' 64-50 win over Utah in the quarterfinals of the Mountain West Conference tournament Thursday night after taking an elbow to his back shortly after halftime.
Leonard still managed to score 13 points and pull down 12 rebounds in 25 minutes as the Aztecs (30-2) secured the first 30-win season in their 90-year history. He left the bench at one point and lay face down in the tunnel while the training staff tended to him.
"I looked around when I was going to put him back in and said, 'Where did he go?'" Fisher recounted. "Yeah, it gives you concern. He never asks to be taken out -- he asked to come out. He said he got elbowed in the back and it cramped up on him."
Leonard returned to the court but took a seat for good over the final seven minutes.
"I think it was more precaution on my part," Fisher said. "When we took him out about seven, eight minutes to go, I didn't want to sit him for three or four minutes and put him back in. I told him, I don't think I'm going to put you back in. It was not that I was fearful that his back was an issue, but I just wanted to make sure he didn't go in, stiffen up going back in."
Afterward, Leonard downplayed his distress.
"Just a little cramp," he said. "I'm fine now. Just need to get it stretched out. But it's no serious injury."
The Aztecs (No. 6 ESPN/USA Today, No. 7 AP) can ill afford that if they're to fulfill their dream of a deep run in the NCAA tournament.
"To be honest, I didn't notice" Leonard's game slip at all after he got hurt, Utes center David Foster said. "He's a tough player. He seems to play through injuries just fine. There isn't much I noticed on the defensive or offensive end."
With Leonard on the bench down the stretch, Malcolm Thomas shined, finishing with 13 points and 10 boards and coming up two assists short of a triple-double.
The Aztecs, who have beaten everybody on their schedule except BYU, started out slowly against the seventh-seeded Utes (13-18) but closed the first half on a 16-3 run to take a 30-15 halftime lead.
The Utes used a zone almost the whole game to keep the faster Aztecs in front of them, but Jamaal Franklin helped thwart that strategy by sinking a trio of 3-pointers in four attempts.
"He should demand more playing time," Fisher said, smiling. "And he already has."
With all the talk about whether the top-seeded Cougars can rediscover their mojo following the suspension of sophomore center Brandon Davies for violating the school's honor code, the Aztecs have stayed a bit in the shadows even though they're in the midst of their best season.
After never posting 25 wins in the first 87 years, they've done so three straight times, and their 30 wins are four more than their previous high-water mark set two years ago.
"That's a lot of wins," Fisher said. "I think we've earned them. We found different ways to win. We've won when we've made 20 straight free throws. We've won when we haven't made a 3-pointer. We've won in a lot of different ways. I think that's a mark of a good team.
"The one thing we have won with consistently is pretty solid defense. We can be a hard team to score on even when you get it into scoring areas. We have to stay that way."
The Utes closed to 32-23 early in the second half but the deep Aztecs responded with a dazzling display of athleticism and speed that swept them to a 52-29 lead with 9 minutes left.
Utes coach Jim Boylen, who guided Utah to the tournament championship in 2009, said he wasn't worried about his job security after the trying season, insisting his team was on the verge of big things as the program moves to the Pac-12 next year.
"The league was very powerful this year. It was very good top to bottom. It was not a good year to be in a rebuilding mode with five guys that never played Division I basketball," Boylen said. "But I'm encouraged and I like this group. ... I haven't worried about my job status at all."
