The Buffalo Bills tight end and New Jersey native was diagnosed with myocarditis, a condition sometimes associated with COVID-19.

The Buffalo Bills have announced that tight end Tommy Sweeney will miss the remainder of the season after being diagnosed with myocarditis, a heart condition associated with COVID-19.

Sweeney, in the midst of his second season with the Bills, was placed on the COVID-19 reserve list on October 24 after he was deemed a close contact when fellow tight end Dawson Knox tested positive for the virus. He had yet to appear in a 2020 game due to a foot injury prior to Knox’s positive test. The Ramsey, NJ native joined the Bills as a seventh-round draft pick out of Boston College last season and earned 114 yards on eight receptions in his debut campaign.

“I saw him today, he’s in good spirits,” Bills head coach Sean McDermott said, per The Buffalo News. “He’s had a rough year, with the injury, COVID, and residual piece of the COVID, unfortunately. We know he’s a good football player and a guy that we believe in and can’t wait to get him back on the field when he can in the offseason.”

According to WebMD, myocarditis is “inflammation of the heart muscle (myocardium)”. Symptoms include shortness of breath, abnormal heartbeat, light-headedness, and joint pain. Though the full extent of its direct association is unknown, the rare viral disease has been found in COVID-19 patients, even those who have recovered. Boston Red Sox pitcher Eduardo Rodriguez was diagnosed with myocarditis after a bout with coronavirus in July, who sat out the shortened 2020 MLB season to recover.

The Bills (7-3) are set to return to action this weekend following their bye week. They’ll host the Los Angeles Chargers at home on Sunday afternoon (1 p.m. ET, CBS).
