Remember when Christian Eriksen - an incredibly fit soccer player - WENT INTO CARDIAC ARREST (EDIT) at the European championships in June?

And Eriksen definitely hadn’t just been vaccinated for Covid.

Except maybe he had. In a radio interview in May, his Italian team doctor had suggested the team’s players WERE BEING vaccinated at the time or WOULD be vaccinated before the 2021-2022 season; the translation of the statement was equivocal, and the interview has since disappeared.

Eriksen has never made any definitive statement either way, and in fact has nearly vanished. He was in the news for the first time in months when his professional team, Inter Milan, said he would not be able to play in Italy this year.

Anyway, it just happened again. Another top-flight European player has just been hospitalized for chest pains. Fortunately Sergio Aguero, the striker for Barcelona, apparently did not have a heart attack. He is currently under observation.

Keep in mind these are among the best-conditioned athletes in the world.

Gee, I wonder what could have happened?

Then there’s the curious case of Trey Potts, the starting running back for the University of Minnesota Golden Gophers.

At least Potts was the starting running back until Oct. 2, when he left Minnesota’s game against Purdue University with an unexplained injury. Potts walked off with “no immediate signs on the field that he had been hurt in the first place,” per a Minnesota newspaper - but then was taken by ambulance to a hospital and hospitalized for six days.

The university now says Potts - who as a student was required to receive a Covid vaccination - will not play again in 2021 because of an “upper-body injury,” a weirdly, if not insultingly, vague diagnosis.

We should probably check with Dr. Rochelle Walensky or some other public health professional, but the heart is in the upper body, right?

NOTE: The headline of this article initially incorrectly said Eriksen had suffered a heart attack; in fact he suffered cardiac arrest, meaning his heart entirely stopped beating, a condition often but not always caused by a heart attack.

I regret the error.

Also: PURDUE, not Perdue. Two in one story after a very long clean sheet. Ugh.
