“The on-field officials make an onside/offside judgment and that will be considered correct unless the VAR identifies, in their opinion from looking at the footage, a clear and obvious error.
[It] will then be deferred to the match referee to make a final judgment by reviewing the footage at the pitch-side monitor.”
-- Howard Webb
, PRO general manager in charge of
officials in MLS, the NWSL and USL, on MLS's use of VAR, which will not be done in 2020 with the virtual offside line technology that has caused controversy in the Premier League. After tests were
done in 2019, it was determined MLS games don’t yet have enough TV cameras to make the use of the technology consistently viable. (Philadelphia Inquirer
