Here's what the tentative 2nd round schedule looks like:
Game 1: Thursday, April 25, 7 p.m. ET @ Boston (NBC Sports Network)
Game 2: Saturday, April 27, TBD @ Boston
Game 3 (IF Washington advances): Monday, April 29, TBD @ Columbus
Game 3 (IF Carolina advances): Tuesday, April 30, TBD @ Columbus
Game 4: Thursday, May 2, TBD @ Columbus
*Game 5: Saturday, May 4, TBD @ Boston (if necessary)
*Game 6: Monday, May 6, TBD @ Columbus (if necessary)
*Game 7: Wednesday, May 8, TBD @ Boston (if necessary)
Game 1 is the only game that's officially set with TV network, date and time all announced already. The times and TV networks for the rest of the games will probably be officially announced AFTER the Hurricanes-Capitals play Game 7 tonight. All the dates are pretty much figured out though except for Game 3 (which depends on what happens in the CAR-WAS series).
