Alipate and Keise are among the first six current college football players to join the lawsuit, which is challenging the NCAA's right to use their names and likenesses in video games.
The other four current players are Arizona linebacker Jake Fischer, Arizona kicker Jake Smith, Clemson defensive back Darius Robinson and Vanderbilt linebacker Chase Garnham.
The 6-5, 281-pound Alipate, who was recruited as a quarterback out of Bloomington Jefferson, has converted to tight end for the Gophers and has yet to play a down heading into his senior season. Keise, from Coral Springs, Fla., has played sparingly heading into his senior season.
On Wednesday, the NCAA announced it would not renew its agreement with the video game manufacturer EA Sports.
