‘Hewy' had played every one of the 52 games needed to secure the domestic sport's top prize.
Steelers had become only the second club to become back-to-back champions when they beat the Fife Flyers on that final day of the season, which then saw the forward drop out of the top flight to EPIHL team Hull Pirates.
Hewitt flourished in east Yorkshire, becoming Hull head coach, until the pandemic closed down the sport last year.
But then he re-surfaced with Sheffield Steeldogs in the Government-endorsed return to play programme and his form there has seen him draft-picked by Steelers for the upcoming EIHL series.
The 37-year-old further underlined his importance to Sheffield hockey on Sunday when he scored one goal and three assists in the 5-2 home victory over Telford Tigers, which followed a 4-3 away win the night before, against the same opponents.
Telford had been neck and neck with Steeldogs but now trail four points behind with four games remaining in the seven-week series which ends at the end of this month.
Ben O'Connor, Ben Lake, Alex Graham and James Spurr scored the other goals at iceSheffield.
On Saturday, the two teams played out the tightest, most competitive game of the tournament so far.
Jonathan Phillips, the on loan Steelers' captain, scored the winning goal with four minutes remaining.
His effort followed strikes from Graham, O'Connor and a power play goal from Hewitt. Liam Kirk and Lake each notched 0+2.
Former Steelers goalie Brad Day was pulled by the Telford coach with 27 seconds left but the host team couldn't find the equaliser with an extra skater.
Summing up the successful weekend, Dogs' co-owner Roger Williams said: "Saturday was a game either team could have won but our guys really dug in to defend the lead in the final five minutes. It was a great show of commitment to winning and another great performance in goal from Jordan Lawday.
