Widnes continued their perfect start to the season, with an entertaining 32-18 win over Salford.
The Red Devils led 12-8 at the interval, but the home side produced a rampant second-half performance to win through.
Johnson’s effort could be considered an early contender for try of the season, as the former Batley winger broke from his own half and then had the pace and step to leave opposition full-back Rhys Hanbury rooted to the spot.
The away side retook the lead through Theo Fages, but after the Frenchman’s score it was one way traffic.
Firstly Hanbury crossed and then Brown added his brace of tries to wrap up the victory for Denis Betts’ side, who face Leeds at Headingley next Friday.
Salford meanwhile have now lost two consecutive matches, and although there were some good individual performances from the likes of Jason Walton and Jake Mullaney, the Red Devils need to regroup before they welcome Warrington to the AJ Bell Stadium.
