Knicks and Rangers fans in Manhattan and other Time Warner Cable locations better sit down — you may not get to see your favorite teams on television all season.

The three-week-old standoff between the MSG Network, home to both teams, and TWC is nowhere near an end and could linger all season, sources familiar with the situation said.

TWC’s tough-as-nails programming chief, Melinda Wittmer, and MSG Media President Mike Bair continue to have phone conversations but as far as any progress, there’s precious little to speak of, sources said.

TWC has said repeatedly it was close to a deal with MSG before the NBA strike ended. But now TWC is objecting to what it says is MSG’s demands for a 53-percent carriage rate increase. Until it backs off that position, little is likely to move.

For its part, MSG is saying the 53 percent jump in its rate isn’t their position — and they want a boost that’s in line with what they’re getting paid elsewhere.

TWC reports earnings Jan. 26, and investors will get an update on fourth-quarter subscriber numbers and perhaps some color on whether the lack of MSG is affecting current quarter trends.

MSG has been encouraging sports fans to switch to a different pay-TV service during the blackout.

Working in MSG’s favor is the likelihood that diehard fans will switch to Verizon FiOS or DirecTV pretty quickly.

But the longer it takes to negotiate a deal, the less people will care about switching.

A TWC spokeswoman said: “There is no update.”

An MSG spokesman said: “We have had no meaningful discussions in over a month and remain miles apart.”

Miller Tabak & Co. analyst David Joyce downgraded MSG this week from buy to neutral, a result of the stand-off.

MSG closed the session flat at $29.53. Year-to-date the stock is up 3.1 percent.
