I suppose it's possible the Union still have everyone available. Possibly a non-player got sick, and the team found out yesterday just as training was to start. So they test everyone and suspend training for the day. They say they resumed training today:
Presumably few enough players tested positive so that's why they were able to return to training. Possibly even zero; possibly a few. But I'm sure they need to keep testing either way.
Between wondering if Sands and Gray can start, who replaces Castellanos, and now this with the Union, this will be one of the most fraught end highly anticipated roster reveals ever in MLS Sunday afternoon.
Also, why does the Union have an "x" in front of their name on Twitter?
