Maryland, which joined the conference this year from the ACC, will play its first Big Ten home game after opening conference play on the road against Indiana.
Heuerman said Ohio State will "welcome" Maryland to the conference.
"We're going to go there and we're going to welcome them to the Big Ten," Heuerman said after practice on Wednesday. "We're going to go on the road and it's going to be a big game and we're going to show them what Big Ten football is and hopefully it'll come out in our favor."
Heuerman's welcome sounded maybe 65 percent neighborly, 35 percent like a warning. Told he sounded like someone offering a warm greeting, Heuerman laughed.
"We'll show you what's up," he said with a smile.
Heuerman has three receptions for 38 yards this season.
Saturday's game will be Maryland's first sellout at Byrd Stadium since 2008. The Buckeyes and Terrapins kick off at noon.
