The 28-year-old returned after almost two seasons on the sidelines against Gillingham in the Carling Cup last week.
Reid made a 45-minute cameo at Priestfield and Allarydce has praised the Republic of Ireland international's professionalism to battle back to full fitness.
"Steven is a super dedicated, model professional in terms of the times you see him with his gloves on, sweating away in the gym on the way to his reconditioning work," he told the Lancashire Telegraph.
"He doesn't just rehab his injured knee, he keeps the whole of his body in immaculate condition. He reminds me of Gary Speed, this guy though didn't get the injuries. He does absolutely everything that is needed to get himself in tip-top condition."
Meanwhile, Rovers' Carling Cup third-round clash at Nottingham Forest will take place at the City Ground on Tuesday, September 22.
