What happened: Siqueira made his MLS debut this month during a 3-0 win. He became the 14th academy graduate to appear for New England.
Why it matters: The contract follows his short-term agreement and gives him a first-team roster place. New England is fourth in the Eastern Conference with 34 points from 21 matches.
By the numbers: Siqueira has two goals and one assist in 14 second-team matches this season, including 10 starts. He has three goals and one assist across 23 MLS NEXT Pro appearances over the past two seasons.
What to watch: His next first-team selection will show how quickly the deal produces regular MLS minutes.
