The youngster joined on loan from Tottenham Hotspur in January.
He has not featured significantly so far, with him still working his way back to full fitness after missing the first half of the campaign with an ankle injury.
And Pulis says they will be continue to be careful with the young starlet as they have an obligation to Tottenham not to risk his long-term fitness.
“Alex has come in and has tremendous talent," he told the Birmingham Mail.
"He was injured at Tottenham for a long time so it's just making sure and I think Tottenham are concerned we don't push him too quickly too soon.”
“The last thing they want is the kid to get injured again, sometimes you have to hold them back and we have a responsibility to Tottenham for that."
While he seems reluctant to risk Pritchard’s long-term fitness, Pulis may be forced to start playing him more often as the season comes to a close.
His side are sorely lacking any sort of creative influence, with them having come in for stern criticism for the unimaginative football that they play.
Pritchard could be the remedy to that having impressed in the Championship this season, and it will be interesting to see if Pulis risks him to ensure his side don’t get dragged into a relegation fight.
