Rush averaged 9.8 points and 3.9 rebounds in 26 minutes per game last season. He shot 45.2 percent from 3-point range — sixth-best in the NBA — and was Golden State's best option off the bench.
"It's a tough time," coach Mark Jackson said Saturday night before the Warriors played the Clippers in Los Angeles. "It's a blow for us, no question about it, because we lose our best perimeter defender. Some teams you probably don't have to address when something like this happens, but this is an extremely close-knit group, and you could tell they were affected as soon as it happened."
Rush was drafted No. 13 by Portland in 2008 after leading Kansas to the national championship. He was then traded to Indiana along with Jarrett Jack and Josh McRoberts for Jerryd Bayless and Ike Diogu.
Rush originally declared for the NBA draft in the 2007 season until he tore the anterior cruciate ligament in his right knee. He never signed with an agent and returned to school, playing for the Jayhawks again only six months after surgery.
Just as he did before, those around him believe he will make a full recovery.
"He's strong minded," Bartelstein said. "Right now it's hard. I have no doubt he'll do great."
