The Timberwolves are investigating whether Martell Webster was significantly injured when they acquired him from the Trail Blazers this offseason.

Portland dealt Webster to Minnesota for the 16th overall pick in June's NBA Draft.

Webster on Monday underwent surgery to repair a disk in his back and is expected to miss about six weeks. He said the injury dates back to last postseason.

The Timberwolves are believed to be trying to get extra compensation in the trade, reportedly a draft pick.

"We're all laughing about it," says one front office executive. "You can't watch the freaking playoffs? That was a pretty obvious incident, right on national TV."

Timberwolves coach Kurt Rambis and Kevin Love have spoken about the forward's playing time and they are on the same page.

The young forward played just nine minutes in the second half against Sacramento on Wednesday night. He finished with 24 total minutes.

Love complained about his role last season and left the locker room Wednesday without speaking to the media.

After practice Thursday Love said he and Rambis are fine and that any speculation about a rift has been blown out of proportion.

Rambis said he spoke to Love in the morning to make clear he had no "hidden agenda" or "loss of faith" in Love.

The Wolves have asked the NBA to investigate whether Portland knew the seriousness of Martell Webster's injury before they traded him on draft night.

Webster underwent surgery to repair a disk in his back and is expected to miss about six weeks. He said the injury dates to last spring's playoffs, when he was undercut and fell hard in a game against Phoenix.

The Wolves are likely looking for a draft pick as compensation.

Jonny Flynn returned to the practice with his teammates on Tuesday after being cleared by doctors on Monday in Vail, Colo.

Flynn is recovering from surgery to repair a torn labrum in his left hip.

"I was told that everything has healed correctly, but I still want to take it slow," Flynn said. "I still have to listen to my body and be cautious."

Flynn is hoping to return to game action by mid-November.

Martell Webster will miss four to six weeks to recover from back surgery.

Minnesota said Webster had the procedure on Monday.

He was hurt in the playoffs last season with Portland and the injury flared up this month.

The Timberwolves are concerned about Martell Webster's back, an injury that was originally suffered in the postseason this past spring when he was with the Trail Blazers.

Webster has undergone an MRI and the team will wait for the results before making a diagnosis.

Minnesota coach Kurt Rambis said the team's concern grew recently when the condition didn't improve.

Timberwolves point guard Jonny Flynn will have his hip re-evaluated on Oct. 25 in Vail, Colorado.

Flynn will travel to meet with Dr. Marc Phillippon, who performed surgery on Flynn's left hip on July 27 to repair a torn labrum.

Flynn has yet to be cleared for extensive physical activity.

The Timberwolves have four of their five starting spots cemented, but the shooting guard role remains unclaimed.

Corey Brewer, Martell Webster and rookie Wesley Johnson will compete for the role, with Wayne Ellington and rookie Lazar Haywood at the position as well.

"I have no idea how it will play out," coach Kurt Rambis said.

"We've had guys play really, really well. Martell's had a really good camp. Wes has had a good camp, Wayne has had a good camp. Corey's been solid. Lazar's been solid. It's a good problem to have."

The Timberwolves defeated the Lakers 111-92 on Monday night in London thanks to 21 points from forward Michael Beasley.

Kobe Bryant went 0-for-3 from the field in just six minutes of playing time. He is still recovering from offseason knee surgery.

Minnesota used a 32-13 run in the third quarter to take control of the game.

"I think we surprised everybody tonight," Beasley said. "I don't think anybody thought we would win. It shows our work ethic and our character. That's what we're here to show this year."

The Timberwolves will start rookie Wesley Johnson at shooting guard on Monday in their preseason game against the Lakers.

Minnesota will also start Luke Ridnour, Michael Beasley, Kevin Love and Darko Milicic.
