As the Miami Heat attempt to record a winning five-game western trip, it's uncertain if a hobbled Dwyane Wade will be available to help. With Wade day to day, the Heat face a Sacramento Kings team that could be missing its second-leading scorer Friday night. Averaging a team-leading 22.1 points and 5.6 assists, Wade missed Wednesday's 104-89 loss at Golden State with a hamstring strain suffered during a 78-75 win over the Los Angeles Lakers a night earlier. Coach Erik Spoelstra said ''rest is on the agenda'' for Wade, who might take a more cautious approach to this injury.
