The NBA unveiled an ambitious schedule of Christmas games to tip off the shortened 2011-12 season on Christmas Day, B&C reports.

The lockout shortened each team’s schedule from 82 games to 66 games and pushed back the start of the season. But the league is hoping to get things off to a big start, with many of the top teams in high-profile holiday clashes. The schedule opens with TNT’s broadcast of the Boston Celtics vs. the New York Knicks at noon ET.

ABC and ESPN take over after that, with a rematch of the NBA Finals — the Miami Heat vs. the Dallas Mavericks — at 2:30 p.m. ET on ABC. Then at 5 p.m. ET on ABC, the Chicago Bulls take on the Los Angeles Lakers.

ESPN will show the Orlando Magic vs. the Oklahoma City Thunder at 8 p.m. ET. The capper for the day is on ESPN at 10:30 p.m. ET, when the Los Angeles Clippers face the Golden State Warriors.

In addition, on Dec. 6 at 7 p.m. ET, NBA TV will preview the season by going over the schedule and promoting the top games.
