Rafa Benitez has allayed fears after Newcastle United's Aleksandar Mitrovic hobbled off against Bohemian.
The striker signalled to come off late in the first half at Dalymount Park on Saturday.
Mitrovic had earlier won and converted a penalty for Newcastle, who went on to comfortably beat the Dublin side 6-0.
Supporters at the game feared the 21-year-old had suffered an injury.
But United manager Benitez said: "It was a knock on his ankle, nothing serious."
Mitrovic will miss the first four games of the coming season through suspension following his dismissal on the final day of last term.
The pair returned home from the club's week-long training camp in Ireland to have treatment on Tyneside.
