LeBron James is prepared to post up for some of his offense with teammate Chris Bosh sidelined because of a sprained ankle.

James said he spent time working on his post game during free agency last summer in case his new team needed him to play some power forward.

Bosh is expected to miss Saturday's game against the Raptors.

"If I'm going to be playing an extensive [power forward], I'll start getting down there and getting us some more paint points," James said.

"I spent a lot of time on it this offseason. Once I made the decision to come here and realized we had a low-post threat, I kind of backed off a little bit. With [Bosh], he's been our outlet. With him being out, I can go back to it. I just have to dust it off a little bit. It's no problem."

Miami is trying to snap a season-high, four-game losing streak.
