In a frightening moment last night, Golden State Warriors forward Brandon Rush injured his left knee in a game against the Memphis Grizzlies.

Rush went up for a dunk in the first quarter when he was fouled from behind by Grizzlies forward Zach Randolph. He then landed awkwardly on his left foot and his knee bent badly.

UPDATE: According to his agent, Mark Bartelstein, Brandon Rush tore his ACL on his left knee. He is done for the year. Here’s his quote from SFGate.Com:

“It’s devastating, but we’ll put a plan together with the Warriors’ medical team, and we’ll get him back to 100 percent,” Bartelstein said. Most athletes miss between nine and 12 months after ACL surgery. “He’s crushed, as you would expect, but he’s a hard worker, and we’re going to get this right.”

Rush had to be helped off the court. He has an injury history as he tore his ACL on his right knee a few years ago. The injury Rush suffered last night understandably left the Golden State Warriors shell-shocked.

From the AP via ESPN, here’s what Golden State coach Mark Jackson said:

“I think that took a little bit out of us,”

Warriors teammate Stephen Curry had the same sentiments.

“When you see one of your brothers go down like that, emotionally, it was pretty tough,” Curry said.

Brandon Rush is scheduled to have an MRI later on today.

Rush was drafted by the Indiana Pacers in 2008 with the 13th overall pick after three years at Kansas. He was traded to Golden State after the 2010-11 season for Louis Amundson. He then averaged 9.8 points and 3.9 rebounds off the bench while shooting a career-high 45.2 percent from deep.

Brandon Rush has two older brothers that played professional basketball. JaRon Rush was more known for his collegiate career as he played in powerhouse UCLA. Kareem Rush played a few years in the NBA. He last played with the Los Angeles Clippers in the 2009-10 campaign. Kareem was probably most known for his stint with the Los Angeles Lakers from 2002-04.

Speedy recovery, Brandon.
