The decision by Washington Capitals star Alex Ovechkin to skip back-to-back All-Star Weekends has the NHL concerned it could start a trend among players, according to deputy commissioner Bill Daly.

"In terms of player participation, is that a concern? Yes, I think it is a concern," Daly told the ESPN On Ice podcast this week.

"I was the first to defend Alex Ovechkin's decision last year to take a year off, because he's been fabulous in terms of helping the league in promoting the sport, including the All-Star event every year. Last year, I was much more willing to look the other way on something like this. But two years in a row is probably something we do need to address with the players' association, so it doesn't become a trend."

Ovechkin opted out of the 2019 All-Star Game in San Jose, California, to rest, following the Capitals' long run to the Stanley Cup championship in the previous season. He will be skipping the 2020 All-Star Game later this month in St. Louis to rest up for the second half of the season.
