Luke Walton re-injures hamstring

ONTARIO, Calif. -- Before the Los Angeles Lakers 105-102 overtime win over the Golden State Warriors began Friday, assistant coach Brian Shaw was asked what his goal for the team's preseason finale and he said he wanted the team to stay healthy.

Shaw might have secured his second-straight win as interim head coach as Phil Jackson missed the Lakers' games on Thursday and Friday with the flu, but he didn't accomplish his goal.

Lakers forward Luke Walton played just 4 minutes, 30 seconds in the first half before re-injuring his right hamstring.

"He looked over at the sideline, felt something, felt it tightening up," Shaw said. "So, I called a 20 [second timeout] so he could come out."

Walton is listed as day-to-day.

Walton missed the first six games of the preseason with the hamstring strain after tweaking it at the start of the team's European training camp tour through London and Barcelona.

The eight-year veteran looked sharp in his preseason debut in his hometown of San Diego on Thursday, collecting five points, two assists and one rebounds in 11 minutes. He also impressed in practice on Wednesday, according to Jackson.

Walton played in just 45 of the Lakers' 105 combined games last season, between the regular season and playoffs, as he suffered from a pinched nerve in his lower back.

The Lakers prepared for the possibility of Walton missing extended time again in 2010-11 by adding two small forwards to the team in the offseason, via free agency (Matt Barnes) and the draft (Devin Ebanks).

Ebanks, who was selected with the No. 43 pick out of the University of West Virginia, finished with six points and four rebounds Friday and caused a key fourth-quarter turnover by Golden State when he drew a charge against Brandan Wright.

"I've been surprised at his poise," Shaw said. "A lot of times, especially young players, they come in and they try to do everything really, really fast. He has some poise about himself as if he's been around for a long time. ... He's a guy that kind of makes it on a coach where you got to find a way to get him in there because he makes things happen when he's out on the floor."
