The midfielder, who has been plagued by hamstring problems this season, was substituted holding his left wrist in the latter stages of Spurs’ 1-0 Champions League quarter-final first leg win over Manchester City on Tuesday.
The Daily Mail report Alli had a scan on Wednesday following concerns he had suffered a suspected broken hand.
The England international could wear a splint or cast to protect his hand while playing, meaning he is likely to be available for Saturday’s visit of Huddersfield.
Alli will be crucial to Spurs’ top-four hopes as they lead fifth placed Arsenal by one point with six matches to go.

Mauricio Pochettino expressed fears that star man Harry Kane could miss the rest of the season with an ankle injury.
The 25-year-old was forced off just before the hour mark of the City game following a 50-50 tackle with England team-mate Fabian Delph.
He left Tottenham’s new stadium on crutches with his left ankle in a protective boot.
Kane missed seven games with the same injury earlier this year.
