Young defender Marshall Willock has joined neighbouring non-league team Matlock Town on loan.
Willock, who was signed from Solihull Moors on a two-year deal last August, will spend the rest of the season with the Gladiators. A recall option has been included in the agreement.
The teenage centre-back had a previous loan spell at Kettering Town, which began in October. He returned to the Proact the following month after suffering an injury.
