Kansas University freshman basketball player Elijah Johnson had arthroscopic surgery on his left knee Tuesday in Lawrence.

The 6-foot-2 point guard/shooting guard, out of Las Vegas’ Cheyenne High, will miss two to three weeks of pick-up ball, KU coach Bill Self said.

“They (doctors) went in and cleaned it up,” Self said of the knee that Johnson hurt in a game back on Dec. 2. “He had a slight cartilage tear he suffered in high school. He was back in class today. He’s fine.”

Johnson — he does not need the use of crutches — remembers when he hurt the knee.

“I tried to dunk on a guy in a game. I came down and hit my knee. It’s bothered me off and on for six months now,” said Johnson, who experienced soreness in the knee last week.

“It was getting irritating. I got it taken care of. I’ll be out 21/2 weeks. It’ll be better than new,” added the player, who is known for his athleticism.
