​It's hard to picture the San Antonio Spurs with a core that doesn't include Tim Duncan, Tony Parker and Manu Ginobili. But that reign is over. Thanks to Gregg Popovich, despite what appears to be a mini rebuild (or re-tool), they're ready to win now.

But it's been confirmed that a promising piece to that rebuild, point guard Dejounte Murray, tore his right ACL during a preseason game against the Houston Rockets on Sunday. 

A timetable for his return will be determined at a later date. For those who were watching football, here's footage of the play when the injury occurred:

It appears as though Murray's right knee buckled in the paint as he prepared to elevate against James Harden on a breakaway drive.

It's devastating news for the former Washington Husky, who is coming off a great season for San Antonio. He appeared in 81 games, averaged 8.1 points, 5.7 rebounds 2.9 assists and 1.2 steals in 21.5 minutes per game. He was named to the NBA All-Defensive Second team, becoming the youngest player in ​NBA history to be named to an All-Defensive team.

​Murray is the second piece of the Spurs young core to go down in the preseason, so this team will have to adapt. Too bad Tony Parker left, right?
