The Miami Herald (Michael Wallace) reports:  The Miami Heat spent Wednesday’s shootaround preparing for Portland Trail Blazers center Greg Oden to make his return from a foot injury that has kept him out since the season opener. Oden doesn’t plan to disappoint Miami (4-3) when the Blazers (4-3) arrive for Wednesday night’s game at AmericanAirlines Arena. ”I’m ready. I’m excited,” Oden said after Portland’s shootaround Wednesday. “I’ll hopefully play the full game. It was my decision and it depends on how I feel. And I feel good.” Oden, the No. 1 pick in the 2007 draft, hasn’t played since he sustained a right mid-foot sprain after playing just 13 minutes in the Blazers’ Oct. 28 loss to the Lakers. He was initially expected to miss as much as a month. It has been another disappointing start to the season for Oden, who missed all of last season after knee surgery.
