Heathens claimed a 19-14 victory at Long Buckby IIs in their opening Youngs Bitter merit fixture of the season.
A bruising match at Long Buckby’s Station Road ground saw joint man of match performances from Heathens winger Sam Berry and full-back Wayne Stride.
Heathens opened the scoring through centre Mark Allison and their lead was extended by Terry Wooldridge.
The conversion was made by Romanian hooker Vio Marin, to leave the score at 12-0 to the away side at the interval.
Long Buckby narrowed the gap to five points after the break, but No.8 Dan Stonehouse dotted down soon after, with flanker Ash Brown adding the extras.
Long Buckby did grab a late converted try, but Heathens saw the game out.
Next Saturday, Heathens remain in merit table action when they take on Vauxhall Motors at home on The Racecourse with a 3pm kick-off.
Towcestrians suffered their first defeat of the season at the hands of fired-up Salisbury.
Salisbury scored first and Tows were soon hit with a yellow card as Callum Threlfall was sent to the bin.
A penalty try made it 14-0 lead to the home side before Wesley Roberts found Chrissie George, who reduced the deficit.
Fly-half Scott Browne followed this with a penalty to get the Tows back in the game at 14-8, but Lane added two penalties to give Salisbury 12-point half-time lead.
Tows responded at the start of the second half with Liam Wilkinson scoring, but again indiscipline proved costly, with two more quick penalties going the way of Salisbury.
James Falvey nipped in to narrow the gap to four points, but another yellow card was to hit hard as Salisbury secured a late penalty.
That denied Tows a losing bonus point and they will now look to bounce back against Leighton Buzzard at Greens Norton Road on Saturday.
Meanwhile, a young Tows IIs side cruised to a 62-3 victory at home to Kettering and the IIIs beat Casuals IIs.
