The NBA is coming up on the All-Star break, but a couple teams could see their NBA betting chances of winning the championship take a big hit courtesy of some ill-timed injuries to key players.

Orlando’s Jameer Nelson should be preparing to make his All-Star debut as the fifth-year guard is having a splendid season. However, Magic fans were left holding their breath when Nelson went down hard in Monday’s 105-95 loss at home to Dallas. Nelson has been diagnosed with a torn labrum and a dislocation in his right shoulder, but he has the option of rehabbing to get through to offseason surgery. Either way, this is a damaging blow to Orlando’s NBA betting odds, as the Magic don’t have a guard close to Nelson’s caliber (although rookie Courtney Lee has looked nice this year).

Out in Tinseltown, Andrew Bynum is wishing that he never has to face the Memphis Grizzlies again. The young center on the West-leading Lakers suffered a serious knee injury for the second straight year against the Grizz, this time coming on Saturday when he was run into by teammate Kobe Bryant. The Lakers’ NBA betting chances should still be in good shape, as they reached the Finals last year without Bynu, but it’s clear they are a much better team with him. Bynum is a major presence iin the post, which opens up the floor for Bryant (Monday’s 61-point explosion in New York notwithstanding) and Pau Gasol. Bynum won’t be back before the playoffs, and even then, it’ll be up in the air.
