The Dutchman picked up the problem during United’s 1-1 Champions League draw against Shakhtar Donetsk earlier this month but was passed fit for Saturday’s 2-1 win over the Black Cats.
However, the 30-year-old striker remains a doubt for the Netherlands’ forthcoming World Cup qualifiers against Hungary in Amsterdam, and Turkey in Istanbul.
“I got an enormous stamp on my toe and I really thought it had been broken but, luckily, a scan showed it was not,” Van Persie said.
“I played on Sunday [in the 2-1 win at Sunderland] but the injury has not got better.”
Van Persie, who won the Premier League title with the Red Devils last term, has scored six goals in all competitions for Manchester United so far this season.
