An MRI is scheduled today, but Harris says there’s nothing to worry about. His coach, though, feels a tad differently. The NY Post has the reactions: “Harris said he was fairly unconcerned about missing any extended time, but he did admit the MRI exam is needed to ensure he didn’t tear his meniscus. But the coach feels otherwise. ‘We are concerned,’ Johnson said. ‘We’ll have to see how it goes. But MRI [exam today], and we’re just hoping and praying for some good news.’  This is just another blow for the 6-12 Nets, who likely will suffer if Harris is out for an extended period. He’s averaging 17.7 points and 6.6 assists, and though Jordan Farmar is a solid backup, he’s not Harris. If Harris is out, third-stringer Ben Uzoh could become Farmar’s backup. ‘Devin is a guy that we rely on heavily,’ Johnson said. ‘In a sense, it’s kind of like if [the Knicks] lose [Amar'e] Stoudemire.’ Despite the concern, Harris sounded optimistic. ‘[The knee] feels pretty good,’ he said. ‘We’re going to do an MRI [today] to rule out a meniscus tear. Can’t really rule anything out till then. It’s a little bit stiff right now but all in all, it’s not too bad. I’m not that worried. The doctor said it was pretty stable when he was doing his little knee [exam].’”
