Ray Allen scored 28 points Wednesday night to lead the Boston Celtics to a 92-81 preseason win over the Minnesota Timberwolves in Kevin Garnett's first game against his former team.

Garnett, who spent 12 years in Minnesota, scored nine points in less than 30 minutes at London's O2 Arena, but he helped in other ways.

"When you have KG in the post, everyone wants to double him," said Allen, who was 5-of-8 from 3-point range. "We can knock down 3s. We have so much available."

Garnett had six rebounds, two assists and three blocks.

"The past is the past," Garnett said. "This is a new chapter in my life."
