The Celtics could use a little help - OK, they could use a lot of help - in improving their defense.

Help appears to be on the way in the form of Avery Bradley, who is expected back the game Sunday against Orlando.

"I don't see any reason why right now why he wouldn't play on Sunday," Celtics coach Brad Stevens said after a 95-94 loss to Philadelphia on Wednesday.

Bradley sustained a right ankle sprain in the first half of a loss at Miami Jan. 21.

Boston has lost four of the five games without Bradley since the injury.

An All-NBA second team defensive selection last season, the Celtics are a weaker team without their defensive ace in play.

With Bradley, opponents were averaging 98.6 points per game, the 11th best scoring defense in the NBA at the time. Since then, they have slipped to 99.1 points and are ranked 13th in the league.

Looking back at Boston's latest loss, there's a good chance that Bradley would have been on the floor instead of Jerryd Bayless on Evan Turner's game-winning shot.
