You can watch the upcoming Dallas Mavericks vs. Portland Trail Blazers game on national TV and legal streaming via NBC and Peacock, with additional options depending on your location and subscription. Many fans also follow along with live scoreboards and play‑by‑play streams on platforms like YouTube and major sports sites.

Main ways to watch

  • National TV & streaming (US): The latest December matchup is part of the NBA package carried by NBC, with a national telecast and a simultaneous stream on Peacock in the United States. Tip‑off for the current NBC/Peacock game is listed around 10:30 p.m. ET from Moda Center in Portland, so check your local listings in case times shift slightly.
  • Team & league platforms: NBA games like Mavericks vs. Trail Blazers are often available through NBA League Pass in markets where local blackout rules allow, so out‑of‑market fans can stream the game there if it is not exclusive to a national broadcaster. Local regional sports networks in Dallas and Portland sometimes carry non‑exclusive games, but those games will usually be blacked out on League Pass inside each team’s home territory.

Live streaming options

  • Peacock: NBC’s streaming service is carrying this season’s Monday NBA packages, including Mavericks vs. Trail Blazers in the current schedule, with a live stream accessible via the Peacock app or website. Peacock requires a paid subscription, but once signed up you get access to the full game plus other NBA Monday content and on‑demand replays.
  • Scoreboard/live commentary streams: Some creators run live play‑by‑play and real‑time scoreboards for Blazers–Mavs on YouTube, letting you follow every possession even if they do not show the TV feed itself. These streams are helpful as a second‑screen companion or if you cannot access the official broadcast but still want detailed, moment‑by‑moment coverage.

What to avoid

  • Unofficial “free HD” sites: A number of pages advertise “free” Mavericks vs. Trail Blazers live streams with vague or misleading descriptions that reference other sports or reuse generic text. These sites are often low‑quality, potentially unsafe, or unauthorized, so it is better to stick to official broadcasters (NBC, Peacock, League Pass, or your regional sports network) and reputable platforms.

TL;DR: For “where to watch Dallas Mavericks vs Portland Trail Blazers,” start with NBC on TV and Peacock for legal streaming, then consider NBA League Pass or your local RSN if the matchup is not nationally exclusive. Always avoid shady “free” stream links and lean on official TV partners or well‑known apps for the best and safest viewing experience.
