Just clocked this on the RFU website:
Statement on Jonathan Kaplan
Brian Smith and Jonathan Kaplan have discussed the recent comments made by the England Attack Coach following the RBS 6 Nations match against Wales.Brian Smith said: “We have spoken since the Wales Test match and I believe it was a positive conversation. I apologised for expressing my views publicly because it would have more productive to have raised those directly with him after the match.
“Jonathan is one of the best referees in the world and I’m sure we’ll continue to have a healthy working relationship.”
