"I'm fine, given the circumstances," Carlos Ramos told Tribuna Expresso in Portugal.
"It's a delicate situation, but a la carte arbitration does not exist. Do not worry about me!"
Ugly scenes marred the match at the Arthur Ashe Stadium on the weekend, as 23-time grand slam winner Serena Williams lost 2-6, 4-6 to Japan's Naomi Osako, receiving three code violations in the process.
Williams, 36, was first warned for receiving coaching from the stands, before later being docked a point for smashing a racquet in the second set.
