An MRI exam conducted yesterday on the right calf of 76ers guard Andre Miller revealed a strain, and he is officially listed as day to day with the team set to visit the Miami Heat tomorrow.

The injury, which Miller suffered during the third period of the Sixers' 101-89 loss to the visiting Denver Nuggets on Wednesday, could end the veteran's streak of consecutive games played at 501. That is the NBA's longest among active players. Tayshaun Prince of the Detroit Pistons is second with 465.

Miller was unavailable for comment after the team practiced yesterday at the Philadelphia College of Osteopathic Medicine, but coach Tony DiLeo and guard Lou Williams were not counting the Sixers' playmaker out.

"We'll have to wait to see [today], but if it's up to Andre . . . we'll see," DiLeo said. "I think the results [of the MRI exam] were good because it's nothing that's going to be a long-term thing."

Williams, who likely would replace Miller, has never started a game during his four-year NBA career.

"I'm not getting excited about making my first career start," Williams said. "You guys don't know Andre like I do. We don't call him 'The Terminator' for nothing."

Coupled with a 100-91 setback to host Indiana on Tuesday, the loss to Denver left the Sixers with a 27-26 record.

In both of those outings, the Sixers shot poorly, going 28 for 86 from the floor against the Nuggets, and 35 for 91 against the Pacers.

After watching film yesterday, the Sixers worked on both offense and defense.

"Practice was good," DiLeo said. "We tried to clean up a lot of little things."
