Match referee Colonel Naushad Ali will study a video of James Kirtley's action during England's one-day victory over Zimbabwe yesterday.
He will then decide whether to officially report his concerns to the International Cricket Council.
Ali confirmed yesterday he thought "there was a problem" with Kirtley's action after watching him take two for 33 on his one-day international debut in Harare.
He has asked for television replays of Kirtley's performance and intends to look at his action again if he plays in Saturday's second match in the five-match series.
Kirtley said: "I will not be losing any sleep over this because as far as I'm concerned the slate is clean and yesterday was a happy day for me after making my England debut and taking a couple of wickets".
Kirtley was reported two years ago during an unofficial test for England A in New Zealand but was cleared after an investigation by the England and Wales Cricket Board.
