Carolina Panthers owner David Tepper will spend a record $325 million to bring Major League Soccer's 30th franchise to Charlotte, sources have told ESPN.

A Tuesday 10 a.m. ET news conference for what Tepper Sports and Entertainment called a major announcement is scheduled at the Mint Museum in Charlotte. Joining Tepper at the event will be MLS commissioner Don Garber and Charlotte mayor Viola Lyles.

Last week, the Charlotte city council pledged $110 million to help secure the bid against other cities. The $325m Tepper will spend far exceeds the $200m for the 28th and 29th expansion franchises.
