MIAMI — Chris Bosh has been telling the Miami Heat that he’s ready to play.

The Heat seem ready to listen.

And Game 5 of the Eastern Conference finals — which wouldn’t be lacking for drama with Boston and Miami tied at two games apiece — may have another significant layer of intrigue.

Bosh’s status was upgraded to “day-to-day” by Heat coach Erik Spoelstra on Monday, the first deviation by the team after more than three weeks of simply saying his absence was indefinite because of a strained lower abdominal muscle. Spoelstra wouldn’t guarantee that Bosh plays in Game 5, but opened the door to there at least being a chance of the All-Star forward-center suiting up.

“He’ll get a vote,” Spoelstra said of how much Bosh’s input will matter in determining when he takes the floor. “Again, everything is heightened right now. These are extreme circumstances. Everybody will be involved in the decision, if and when it happens. But you always have to take the player’s opinion with a grain of salt. They all say they’re ready. ... He said he was ready 10 days ago.”

The Celtics were ready for him then, too.

So if Tuesday is the Bosh comeback night, Boston will not be caught off-guard.
