Several members of the Pompey squad were involved for their loan clubs over the past week.
The keeper played in Chelmsford's midweek match at Aveley, with a 2-1 victory keeping them inside the National League South play-off places.
And he then kept a clean sheet at the weekend, as the Clarets won 2-0 on the road at Harborough to reach the third round of the FA Trophy.
That latter result came despite the visitors having Ben Brookes sent off midway through the second half.
It was a rare off day for the teenage keeper as Gosport were beaten 2-0 at Chesham in the Southern League Premier.
He conceded a penalty and was sent off in the second half for bringing down Ricky German inside the box.
That meant former Pompey academy defender Harvey Rew had to go between the sticks for Boro for the closing stages.
The midfielder was handed a rare start by Havant & Waterlooville in their midweek Hampshire Cup defeat to Bournemouth at Westleigh Park.
He then came off the bench early in the second half at Totton on Saturday, as the Hawks lost 2-1 to exit the FA Trophy.
