Chris Bosh's sprained left ankle is improving, but he did not practice with his teammates on Thursday.

His status for Miami's game against Toronto on Saturday remains questionable.

The Heat have lost a season-high four games. There is a chance that Bosh could return to practice on Friday, according to coach Erik Spoelstra.

He suffered the injury last Saturday when Bulls center Omer Asik inadvertently dove into Bosh's legs as the two were chasing a loose ball.
