Lingard, 28, has been in sensational form for the Hammers since arriving from Manchester United on loan in January, and added to his tally at St James' Park with a penalty to make it nine goals for Moyes' side this season.
However, the Englishman was seen hobbling off in the latter stages of the game in Tyneside to the concern of West Ham fans amid an injury pile-up at the east London club.
Moyes has insisted, though, that the problem suffered by Lingard was "nothing serious" following their setback against Steve Bruce's strugglers.
"I think it was just cramp, I don't think it was anything serious," Moyes told reporters after the game. "I think the one thing about Jesse, Jesse is a really fit boy.
"He wants to play. I think I push all my players hard, Jesse is no different. He won't get any favoured treatment - certainly not for a Scotsman going into the Euros! We're really pleased with him."
