This figures to be a hectic day, what with the Lakers practicing and then flying off to snowy Minnesota for the start of their six-game trip Friday. We might learn whether Trevor Ariza is fit enough to join his teammates for the flight after suffering a concussion in Tuesday’s double-OT loss to Charlotte. We also might find out of the league will suspend and/or fine Andrew Bynum for sending Charlotte’s Gerald Wallace to the hospital with a broken rib and collapsed lung. As if that’s not enough, we will also learn the names of the All-Star reserves during TNT’s pregame show at 4 p.m. Pau Gasol is expected to make it, although he had better hope it’s not based on his last game. Gasol had a real stinker against Charlotte.
