Heat guard Dion Waiters said he will consider having surgery this offseason on his ailing left ankle, admitting Tuesday the ankle will not fully heal until he goes under the knife. Waiters, who missed the final 13 games of last season with a bad sprain of the same ankle, missed his second straight game after tweaking the ankle in Friday’s win over the Dallas Mavericks and said he’s not sure when he will be back, but does not expect to be out as long as he was at the end of last season. Waiters said strongly he would not have surgery on the ankle until after the season. “Until I take care of it and do what I’m supposed to do with it, even if I have the littlest sprain, it’s going to be like severe,” Waiters said. “That’s why it just sucks because when I watched [the replay of the injury Friday], I didn’t even do nothing. When I twisted, I just twisted it.” Waiters, who decided not to have surgery on the ankle this summer in part because he was a free agent, said at this point he has to consider surgery after the season a real possibility.
