"I'm heading up to Louisiana-Monroe (today) for a visit and I will be there until Friday and then once I get home, I'll turn around I will visit Colorado State on Friday.
"After I get home on Sunday, I'm going to sit down and I plan on making my decision then on where I will sign."
Fox said he's started to think about what will help him decide on which program will fit him best.
"My comfort level with the coaches is a big key for me," Fox said. "Will they take care of me and help me get to the next level, but also will they help me graduate and get my degree?
"I also want to go to a winning program. One that I feel like we can win and play in some big games."
As a redshirt freshman for the Panthers this season, Fox worked his way into the defensive line rotation and finished with 16 tackles, one sack and one tackle-for-loss.
"I can play both (nose tackle and three-technique), but I played more of the three this past season for us," Fox noted. "I come off the ball well and I like to get a lot of pressure up the middle on the quarterback.
"Collapsing the pocket is fun and it helps our defense get off the field. No quaterbacks like getting pressure right in their face, so that's something I try and do every time."
Fox signed with Butler out of high school and redshirted his first season there before transferring to Ellsworth last spring.
He'll finish up his two-year degree in May and he will have three years to play three starting this fall.
