The Heat expects Mario Chalmers to miss two weeks, possibly a bit longer, with a sprained right knee, but team president Pat Riley said Sunday he has no plans to sign another point guard.

Mike Bibby will replace Chalmers in the starting lineup, and coach Erik Spoelstra said Dwyane Wade and LeBron James “obviously will be handling the ball quite a bit, as they have been, but Mike Miller will handle, too. And Eddie House now will step in and take up some of those minutes.”

Riley said “we do feel like we have enough depth to make up for” Chalmers’ absence.
