Get ready for the Darius Morris era, Los Angeles Lakers fans.

Lakers coach Mike D'Antoni said Morris, a seldom-used, second-year guard, likely will start Friday's Game 3 against the San Antonio Spurs because of injuries to Steve Blake and Steve Nash.

Blake is out indefinitely after an ultrasound Thursday confirmed a moderate strain of his right hamstring.

Blake left Wednesday's Game 2 loss to the Spurs with 4:51 remaining in the fourth quarter and had to be helped off the court by teammates after the game. He hurt his hamstring while driving to his right and trying to beat his man off the dribble when he felt a "sharp pain."

The 10-year veteran had been averaging 14 points, 4 rebounds, 2.5 assists, 2 steals and 1.5 blocks in the playoffs while shooting 41.7 percent from 3-point range, but just 39.3 percent overall.

The Lakers, down 2-0 in the first-round playoff series, list Nash as doubtful for Friday's game after he received two epidural injections in his back and a cortisone shot in his right hip Thursday.

"I'm not too bad," said Nash, who tweaked his right hamstring pushing the ball up the court just before halftime Wednesday. "Obviously I wish I felt a lot better, but I got the procedure done [Thursday] morning and fingers crossed it will help.

"I have been called a doctor of chemistry by some people in the media, but I couldn't make a prediction."

Nash, who missed the Lakers' final eight regular-season games because of nerve damage in his right hamstring stemming from a right hip injury before coming back to average 12.5 points and 4.5 assists in the postseason, said there is "absolutely" a chance he does not play Friday.

"I'm very concerned," Nash said. "It's really frustrating. Very, very frustrating. Especially because I was at the point where I was actually excited with the way I felt to start the last two games even though I still couldn't sprint completely and I was not moving as well as I'd like, I felt like I could still be effective and find a way to help the team and impact the game."
