Fans on Twitter seemed to enjoy the cameo as well.
However, it appears that Sheeran wasn't the only celebrity that #GameOfThrones had up its sleeve this year.
"I thought at one point I was gonna be a Knight of the Night's Watch, but I'll be a Lannister and I'll get killed by a dragon", Syndergaard said Monday, while hosting the Citi Noah Syndergaard Baseball Camp at Sportika in Manalapan.
Syndergaard left fans to speculate when he'd make his appearance and how.
"Take that you mean Dothraki", Syndergaard tweeted after the episode, which he followed up with another tweet in which he wrote, "To my sides defense... they had a FRICKEN DRAGON!" In the middle of the Lannister army, on the spear brigade, was Mets' star pitcher Noah Syndergaard, aka Thor, who made his small screen debut in the massive battle between the Lannisters and Daenerys' Dothraki army. He's known for throwing flames, with a fastball that tops out at over 100 miles per hour, and quite appropriately, he tossed a spear through the heart of a Dothraki soldier. Simply put, many viewers don't like it when #GoT breaks the authenticity of the world of Westeros.
