The only pro I know who developed myocarditis was Tommy Sweeney:

Note that the Wisconsin players "had mild (71 [49.0%]) or moderate (40 [27.6%]) symptoms during the acute infection or were asymptomatic (24 [16.6%])."  Of the two who developed myocarditis was minimally asymptomatic:

This patient was initially asymptomatic and tested for COVID-19 as a part of routine screening. At 1-month MRI re-evaluation, the LGE findings were unchanged, but T2-weighted signal abnormalities had improved and the troponin-I level was normal. Clinical follow-up 1 month after the MRI revealed 1 episode of mild dyspnea, but the patient was otherwise asymptomatic.

The other player was initially symptomatic, but asymptomatic at the time of the MRI:

This patient had mild to moderate symptoms (eTable 3 in the Supplement) lasting at least 3 days but was asymptomatic at the time of MRI.

I know the BigTen required MRI's for student-athletes as part of their COVID-19 follow-up. Based on the article above, so did the NFL (I would imagine that all professional leagues would).  But I don't think it was the standard of care everywhere, so there may have been more cases of myocarditis that we never found out about because they weren't tested.  Of course, if they weren't symptomatic, would myocarditis identified on imaging be clinically significant?
