Most injured "star" players travel with the team. Because, you know, "team". Watching MLB this summer and Aaron Judge was on the IL for 15 days the last few weeks and with the team each game. Gerrit Cole is out for the season after Tommy John surgery and won't pitch till next year and I see him in the dugout all of the time.
And this WNBA roadie was hardly cross country, Chicago to Indy isn't exactly crossing multiple time zones and staying in hotels for a week. Plus you have the hyped up personal and team rivalry expectations and both are injured, you'd think the Sky and TV fans would like to have seen her there.
