Giants quarterback Eli Manning seems to be on board with Donald Trump's proposal to build a wall — at least on the field.

Manning appears to be using 'Trump' as an audible call, which was heard during the second quarter of Sunday's Giants vs. Rams game in London.

'Trump! Trump!' Manning yells repeatedly to his offensive line.

The audible appears to be a call for a defensive adjustment — perhaps a shoutout to the Republican candidate's promise to build a wall on the Mexican border.

Fans on Twitter were quick to react.

'I guess Eli Manning wants to #MakeAmericaGreatAgain as he's using "TRUMP" as one of his calls at the line this morning,' wrote Joe Curci.

'Eli Manning calls out Trump on his plays?! Wtf. This is Hillary Country,' sounded off Manish Thakur.

One fan even called out Patriots quarterback Tom Brady, a notorious Trump supporter.

Heard Eli Manning made a "trump" call at the line of scrimmage?' tweeted ezy06001. 'Come on Tom Brady - your turn'

Manning's older brother, Peyton, was famous for his 'Omaha' call, which became a trademark of his.
