A new NWSL campaign kicks off this weekend with the opening games of the Challenge Cup. This is one of the headliners, as Jessica Fishlock and Rose Lavelle lead the Reign against Sophia Smith, Christine Sinclair and the Thorns. It’s the first game for the Reign with Seattle’s Lumen Field as their full-time home, after spending the last few years an hour south in Tacoma.

The first game of the Challenge Cup is earlier Friday: Racing Louisville hosts the newly renamed Kansas City Current (7:30 p.m., Paramount+).

The men’s FA Cup quarterfinals also take place this weekend, and this game will have the biggest spotlight because of the controversy surrounding Chelsea. The London club wasn’t able to sell tickets to its fans who will travel north, so proposed having the game behind closed doors. A huge public backlash led to a reversal of that before the FA could officially dismiss the idea.

Yes, El Clásico is only on ESPN+ again. Why? There are plenty of reasons, but here’s one worth highlighting.

When La Liga set the kickoff time for Barcelona’s home game vs. Real last October, the word went around that this game would have a better kickoff time for U.S. audiences. It certainly does.

But the date of the game is bad luck, because almost all of ESPN’s channels — including ABC — are booked up with college sports: the women’s basketball and ice hockey NCAA tournaments, and the men’s basketball NIT.

Only ESPNews doesn’t have live programming at that hour, and there ESPN made a choice to not put the game on such a lesser channel. Nor will the game be live on Spanish-language TV on ESPN Deportes.

So ESPN+ it is, and we’ll have to wait until next season to see if we’ll get a Clásico on ABC.
