Trey Lyles finished with a game-high 26 points and 11 rebounds, but the Utah Jazz lost 89-82 to the Boston Celtics and fell to 0-2 on Tuesday night at Vivint SmartHome Arena in the Utah Jazz Summer League.

"I take the loss personally because I'm the leader of this team and they all look for me for guidance and knowledge," Lyles said. "I'm definitely embracing the role and trying to do the best I can."

After a loss on Monday to the San Antonio Spurs, the Jazz had a lot to clean up. On Tuesday, the Jazz, who appeared more comfortable as a team, limited the Celtics to 28 points in the paint — having allowed 40 points in the paint to the Spurs — and held Boston to 30.8 percent shooting from the outside.

But the Celtics were able to draw fouls when they did penetrate into the paint, which led to 37 free-throw attempts.

"The thing that hurt was fouling once they got to the paint … we have to do a better job of showing our hands and being disciplined," Jazz summer league head coach Johnnie Bryant said.

Along with Lyles' big night, the Jazz were led by 29-year-old journeyman Dionte Christmas and NBA Summer League newcomer Spencer Butterfield of Utah State. Christmas finished with 14 points, while Butterfield added eight points and five rebounds.

Butterfield started at guard for the Jazz after Olivier Hanlan was traded Tuesday afternoon to the San Antonio Spurs in exchange for Boris Diaw.

Leading the Celtics were James Young and Terry Rozier. Young finished with a team-high 17 points and five rebounds, while Rozier, who has been impressive in two games, added 16 points, six rebounds and four assists. No. 3 overall pick Jaylen Brown sat out Tuesday's game after suffering a hyperextended right knee in Monday's opening game against the Philadelphia 76ers.

The Jazz Summer League has a day off on Wednesday before the third and final doubleheader of the week on Thursday night at the Huntsman Center on the University of Utah campus. The Celtics will play the Spurs at 5 p.m., followed by the 76ers against the Jazz at 7 p.m.
