The Minnesota Timberwolves’ franchise player is out indefinitely with a torn ACL.

The team made the announcement Monday after a somber practice. Coach Kevin McHale said Jefferson will likely have surgery to repair the injury in the next week to 10 days.

“Al’s played at such a high level for this team and been such a big part of our team,” McHale said. “Everybody around here today is a little bit down in the dumps.”

It was devastating news for a young Timberwolves team that has been playing better in 2009 after getting off to a 4-23 start to the season. With Jefferson the focal point, the Wolves went 10-4 in January, and the 24-year-old center was playing even better early in this month.

“I feel terrible for Al. Al’s really, right now, devastated by it,” McHale said. “It all happens for a reason. It’s hard for me to figure out what this reason is. Somehow he’s just going to have to make the best of it and rehab and get better and move on from here.”

The T-Wolves made news back in early December when they fired Randy Wittman and replaced him with then-GM Kevin McHale. At that point, the team was 4-15, and they went on to lose their next eight games to fall to 4-23. Then something strange happened: they started winning. They actually went 12-4 over the next 30 days, a run that included wins at Phoenix and at home against the Hornets. During that span, Jefferson averaged 23.0 points and 11.4 rebounds (numbers that are about the same as his season aveages), and was even getting some love as a possible All-Star (albeit as a long shot).

So Jefferson has to undergo surgery and start rehab, but what do the T-Wolves do now? The team finally started to show some life under McHale — does he get another full season at the helm?
