Malone fouled hard in first quarter
With the Lakers trailing 9-2, Malone fell to the floor and grabbed his knee after being fouled by Scott Williams.
After a brief delay, Malone made one of two free throws before leaving the game 10 seconds later and walking to the Lakers' locker room.
A team spokesman said X-rays didn't reveal any damage, but Malone will have an MRI exam Monday.
Malone, the NBA's second-leading career scorer behind Kareem Abdul-Jabbar, has missed only 11 games in his career -- six due to injuries or illness and five because of suspensions.
The 40-year-old Malone joined the Lakers as a free agent last summer after playing 18 seasons for the Utah Jazz.
