Warriors forward David Lee might be done for the season because of a groin injury.

"The doctors called me and said you've got to shut this guy down," Warriors general manager Larry Riley said.

The morning after scoring a game-high 30 points in a loss to Dallas, Lee had an MRI in an attempt to find the source of his pain. Friday's MRI revealed a strained groin and a stress reaction. Team doctors told Lee if he played before his groin were fully healed, he would risk further injury.

"He wanted to play, but I'm not going to let him," Riley said. "But I told him he could hurt that thing even worse. I'm not going to let him play until he can't hurt it anymore."

The Warriors have eight games remaining. The key for Lee is to rest and let his injury heal. He'll be evaluated periodically.

Riley said he'll have no problem holding out Lee for the final two weeks of the season but didn't rule out Lee playing before season's end.

Lee, who traveled with the team to Los Angeles for Saturday's game against the Clippers, had been experiencing pain for the past several weeks. He couldn't run the floor as well as normal, and his lateral movement suffered.

Still, with point guard Stephen Curry out and guard Monta Ellis traded to Milwaukee, Lee assumed the position of offensive facilitator. So far in April, Lee is averaging 23 points, 9.1 rebounds and 3.6 assists in 37.6 minutes.

Taking Lee from the already undersized and undermanned lineup leaves the Warriors especially thin. Center Andris Biedrins and rookies Jeremy Tyler and Mickell Gladness are the only big men available. Center Andrew Bogut, acquired in the March 13 trade that sent Ellis and big man Ekpe Udoh to Milwaukee, is out for the season with a fractured left ankle.

Warriors coach Mark Jackson will give Tyler a look at power forward next to Biedrins. Jackson can also use one of the Warriors' bevy of small forwards, likely Dominic McGuire or Brandon Rush, to take some of Lee's minutes.

One small forward who won't be available is Richard Jefferson. A sore right knee kept him in the Bay Area for an MRI. There is no timetable yet on his return.

"If we can just get through this year without anybody else getting hurt," Riley said. "That's the big issue."
