Maciel’s rehabilitation is expected to take approximately 8-12 months.
The 22-year-old Brazilian is in his second MLS campaign, notching one assist across 16 appearances (seven starts). Last year, he played nearly 1,250 regular-season minutes as New England won their first-ever Supporters’ Shield title.
Maciel is one of seven former Revolution II players to have ascended to the first team roster. He played for Botafogo in his native Brazil before coming to New England.
