Doc Rivers sure didn’t waste any time bouncing back into the national spotlight.

Thirty-six hours after being fired by the Magic with two years left on his $5.5 million contract, he got himself a top job and marquee money – in TV.

Rivers yesterday committed to being ABC’s lead NBA analyst over the outstretched invitation of TNT, The Post has learned.

Both networks, especially ABC, which was on the precipice of entrusting the microphone to Mark Jackson, pushed hard for Rivers to make a swift decision.

The league’s second all-time assist artist and understudy Rex Chapman were scheduled to do a mock telecast with play-by-play man Al Michaels tomorrow night in L.A., between the Bulls and Lakers.

Now Rivers will be Michaels’ partner for nine regular-season games and the playoffs, culminating with a Finals flourish. After that it’s time for numerous coaches (and GMs) to start sweating. Rivers already is being prominently mentioned as a plausible replacement for Don Chaney (Knicks), Bill Cartwright (Bulls) and Terry Stotts (Hawks).
