Steve Nash needed three injections for pain relief on the Los Angeles Lakers day off.Hes still more likely to play in Game 3 tonight than Steve Blake or Jodie Meeks.And just in case anybody forgot, Kobe Bryant is at home in a walking boot, his season over.Late in a season featuring just about every tribulation imaginable, the Lakers have almost no healthy guards never mind anybody who could keep up with Tony Parker.If they can't cover the gaping holes in their backcourt and figure out how to slow the San Antonio Spurs, the Lakers tumultuous season probably wont extend past the weekend.Los Angeles still has two star big men, but even Dwight Howard realizes this patchwork roster is getting awfully flimsy. He wont use it as an excuse for whatever happens after the Spurs took firm control of the series in Texas.We have total confidence that we can come back and win this series, Howard said after a light practice at the Lakers training complex. We believe in each other. We worked too hard to get to the playoffs. We had to fight to get in. Were not just going to give up because were down and we have a lot of guys that are injured.But the Lakers realize theyre in a tight spot heading back to Staples Center.Nash and Meeks, who has a sprained left ankle, are doubtful for Game 3 when the Lakers attempt to get started on just the third comeback from an 0-2 playoff series deficit in franchise history.Coach Mike DAntoni said Blake is definitely out with a strained right hamstring. Nash attempted to remain optimistic after getting two epidural injections and a cortisone injection his third pain-relieving injections in a week on his sore back and hamstrings.Fingers crossed that it helps at all, and second, that it helps that quickly, Nash said. I have been called a doctor of chemistry by certain people in the media, but I couldnt make a prediction. Im still in a lot of discomfort, not only from last night, but from getting a bunch of darts stuck in me.Garnett hobbling Boston Celtics coach Doc Rivers limited Kevin Garnetts activity during practice on Thursday with the goal of having him ready for tonights Game 3 of an Eastern Conference first-round series against the New York Knicks, ESPN reported.Garnett suffered what Rivers has compared to a hip pointer during Tuesdays Game 2 loss. Garnett didnt address the injury specifically when talking before Thursdays session but said simply that hes confident hell be healthy enough to play.Bryant tweetingKobe Bryants tweets during Lakers playoff games are a hit at the NBA office.Bryant has since decided to stop, saying the focus should be on his team, and Deputy Commissioner Adam Silver said he missed Bryants online commentary.I thought it was fascinating, Silver said at a meeting of Associated Press Sports Editors.Unable to sit on the Lakers bench after his season-ending torn Achilles tendon, Bryant appeared to spend most of their 91-79 Game 1 loss to San Antonio on Sunday online, offering some pointed analysis of what he was seeing.Lakers coach Mike DAntoni called Bryant a fan when asked about the tweets during the game, which Bryant laughed off when he heard it.His coach said, hes a fan now, thats what fans do, Silver said.NBA players are prohibited from posting on social media from 45 minutes before games until they have finished their media responsibilities afterward. Silver doesnt think that rule needs to be expanded to cover players such as Bryant.I dont think we need a leaguewide rule, I think thats a team decision, Silver said. I mean, assuming that the player is not on the bench. Theres an absolute league rule if the player is on the bench, but I mean for a player whos injured who is not sitting on the bench, I think thats a team decision. That should be a team decision as to whether a player should be tweeting.
