Let's try this again.

Last Thursday night, NBCSN televised two NHL playoff games. It had Columbus-Boston shortly after 6 p.m., then Blues-Stars at about 8:45.

The plan was that if the early game ran long, some of the network's customers in the St. Louis and Dallas markets would get the start of Blues-Stars on NBCSN, with the conclusion of the other contest moving to NHL Network. Others would get the beginning of Blues-Stars on NHL Network, with Columbus-Boston remaining on NBCSN.

However, not all systems switched properly, resulting in some viewers missing the start of the Blues-Stars matchup.

“Our overflow scenario for Game 1 of the Stars-Blues series was not executed properly," an NBC Sports spokesman acknowledged.

That scenario could exist again tonight, when NBCSN has Islanders-Hurricanes at about 6:10 p.m. and Blues-Stars at approximately 8:45.

"We have taken steps to ensure that it does not happen again,” the spokesperson said.

Here is what is supposed to happen tonight in the St. Louis and Dallas markets if the early game overlaps Blues-Stars:

• For customers of cable systems (such as Charter Spectrum), plus AT&T U-Verse, the Blues-Stars game is to begin on NBCSN.

• For cable and AT&T subscribers outside the local markets, Blues-Stars is scheduled to begin on NHL Network, then move to NBCSN following the conclusion of Islanders-Hurricanes.

• For satellite customers (DirecTV, Dish, etc.) and streaming services (DirecTV Now, etc.), Blues-Stars is to begin on NHL Network as NBCSN stays with Islanders-Hurricanes until it ends, then picks up Blues-Stars.

• Both games are to be streamed in all markets on NBCSports.com and the NBC Sports app.

Meanwhile, there is a change tonight and Friday in the booth for Blues-Stars, as analyst AJ Mleczko is replaced by Kendall Coyne Schofield. Both have won gold medals for the U.S. women's hockey team.

Mleczko is moving to the Islanders-Hurricanes series to fill in for Eddie Olczyk, who is on NBC's Kentucky Derby coverage over the next few days. Coyne Schofield made her debut as an analyst with NBC Sports this season and has worked as an NHL Network studio analyst.

Kenny Albert returns to do the play-by-play, with Pierre McGuire again serving as the ice-level analyst.

On radio, KYKY (98.1 FM) has the broadcast, with KMOX (1120 AM) joining in progress following its Cardinals coverage. Chris Kerber (play-by-play) and Joey Vitale (commentary) have the call.
