Trump’s Harvard visa threat could wipe out several of school’s sports teams

• Trump visa move threatens 21% of Harvard athletes

• Foreign-heavy teams like crew, squash could fold

• Harvard: Ban unlawful,' vows to fight for students

Some of Harvard's sports teams would be virtually wiped out by a Trump administration decision announced on Thursday that would make the Ivy League school with the nation's largest athletic program ineligible for international student visas.

Seven of the eight rowers on the men's heavyweight crew team that just won the Eastern Sprints title - and is headed to the national championships - list international hometowns on the school's website. Mick Thompson, the leading scorer last season, and Jack Bar, who was a captain, are among a handful of Canadians on the men's hockey roster; 10 of the 13 members of the men's squash team and more than half of the women's soccer and golf rosters also list foreign hometowns.
