Ever had a cotton swab shoved up your nose!? IT SUCKS!
Just ask L.A. Chargers cornerback Casey Hayward -- who had some major pre-swab jitters before his COVID test at the Chargers facility ... and the footage is great!
NFL players are getting tested everyday during the first 2 weeks of training camp -- which opened on July 28.
And, judging by this footage of Hayward captured by HBO's "Hard Knocks" ... there's just no getting used to it!
Both the L..A Chargers and the L.A. Rams are featured on the docuseries this season -- a big change for the show which has traditionally only chronicled one team's journey into the regular season.
