Chicago sports communities — from the Bears to the Cubs’ Jed Hoyer — and NFL figures help raise more than $750,000 for the son of late ESPN reporter Jeff Dickerson

ESPN’s Adam Schefter, who has 8.9 million followers on Twitter, has been promoting the fund on his account by thanking those who donate, including other NFL teams, Jed Hoyer, Theo Epstein, Tom Waddle, Charles Leno Jr. and the Loyola men’s basketball team, for which Dickerson served as a broadcast analyst.
