... I think he intends to retire this year. I believe he is enrolled in the MBA program at Northwestern.
Matt Besler is still on Sporting KC.
Nick Besler is still with Real Salt Lake.
Tommy McCabe is on FC Cincinnati.
Jon Gallager is owned by Atlanta United, but was loaned to Aberdeen in Scotland this season.
Dillon Powers started the season in MLS, but moved to Dundee United in Scotland.
Justin Morrow still plies his trade for Toronto FC.
Another ND notable just retired this season: Harry Shipp
The player who played the longest ago at ND that I could still find playing, in this case abroad, is John Mousinho, who wears the armband for League One side Oxford United. They were contenders for promotion to the Championship before the League One Playoffs were cancelled due to COVID.
It seems Leagues 1 and 2 and the National League eventually had playoffs based on the table standings at the time of the suspension of play. Oxford made the finals, but lost 2-1 to Wycombe. The Premier League and Championship Leagues resumed the regular season.
Thanks for the update.
