"I had an extended opportunity to discuss everything with my family and after those conversations we believed, along with the coaching staff, that Marquette was the best place for me to continue my career," Anderson said.
The 6-6, 210-pounder has appeared in 59 career games for the Golden Eagles, earning 31 starting assignments. He played in all 35 games during MU's 2012-13 run to the Elite Eight and started all but four of the contests.
"After multiple conversations that have transpired over the last month with Juan and his family, he has decided to come back to Marquette and rejoin our program," head coach Buzz Williams said. "He is grateful for this opportunity and I am convinced this is the right thing to do."
