Alex Morgan, a two-time World Cup winner with the US women's football team, has tested positive for Covid-19, the star striker said on Twitter on Tuesday. "Unfortunately, my family and I closed out 2020 learning that we had contracted Covid while in California over the holidays," Morgan, 31, said in a Tweet. "We are all in good spirits and recovering well. After our isolation is completed, I will follow US Soccer's return to play guidelines to ensure my body is fully recovered and I can join my teammates back on the field soon." She had been expected to report to the US women's training camp later in January.
