Higuain was replaced by Federico Bernardeschi early in the Derby della Mole at Stadio Olimpico Grande Torino, an apparent ankle problem prompting fears over the future availability of the Argentina striker.
Bernardeschi was also withdrawn in injury time, but Allegri does not expect either player to spend a significant period of time on the sidelines.
"Higuain received a bruise and we'll evaluate him," he said.
"Bernardeschi left in the final stretch but there shouldn't be any problems.
"Starting Wednesday we'll regroup with everyone available, but in any event the team is feeling well and they showed it today."
Juve host Atalanta in successive Serie A and Coppa Italia matches before visiting Lazio in the league, as they build towards the second leg of their Champions League round-of-16 tie against Tottenham on 7 March.
Spurs rallied from falling 2-0 down within nine minutes at Juventus Stadium on Tuesday to earn a 2-2 draw, leaving the Scudetto holders with a tough task to progress to the quarter-finals when they visit Wembley next month.
