The 18-year-old Blues striker, who completed a one month youth loan deal with The Bulls on Saturday morning, made his debut when being introduced as a 70th minute substitute in the game against The Bantams.
Jervis scored with an excellently executed goal on 81 minutes to help earn Hereford a 2-0 home win on Saturday afternoon.
"I'm delighted to have him at the club. He took his goal very well," Bulls boss Graham Turner told BBC Hereford and Worcester.
"He's just turned up this morning, we got the papers through late enabling him to play.
"He'll get better as he gets used to the players around us."
