Under Armour founder and Maryland uber-booster Kevin Plank is "100 percent" behind the Terrapins moving from the ACC to the Big Ten, a regent told ESPN on Sunday.

The University System of Maryland's Board of Regents will meet at 9 a.m. Monday to vote whether to accept an invitation to join the Big Ten Conference, a source told ESPN.

Plank is "heavily involved behind the scenes with board members," a regent told ESPN on Sunday. The source added that several of the 17 board members were "miffed" that they were not included in the process until the late stages, so the vote could be close.
