Forward Antoine Walker, guard Smush Parker and center Earl Barron were back at practice Wednesday with the Miami Heat, one day after the team held them out of the opening sessions of training camp because of conditioning issues.

"We just decided to give them a little help," Heat coach Pat Riley said.

Riley said the three missed their team-mandated conditioning marks entering camp by slight amounts. The trio worked out on treadmills and stationary bikes in the Heat training room Tuesday, while teammates were put through drills and plays on Miami's practice floor.
