The 6-foot-2, 185-pound 3-star prospect from Fishers (Ind.) Hamilton Southeastern participated in Louisville's first camp weekend and performed well with the Cardinal coaching staff looking on.
"I thought I did really good actually," he said. "I ran my routes really good and I did a good job getting separation from the defense. Not that many balls hit the ground, so I think I had a pretty good camp."
Polk told Cardinal Authority that the response about his performance from the Cardinal coaches was positive.
"They all give my positive feedback," said Polk. "They are going to evaluate the film and they are going to have a couple more receivers down for a visit that they want to look at."
With scholarship offers from Ball State, Indiana, Louisville, Ohio and others, plus interest rising from Kentucky, Northwestern and Purdue, Polk finds the recruiting process both enjoyable and hectic at times.
"It's going pretty good," he said. "I enjoy it and it can be fun, but it can also be a little stressful at times."
Polk, who also camped at Indiana and considered camps at Ball State and Kentucky, has one school that has remained constant at the top of the list.
"I don't have a time frame of when I'll decide, but as of right now, Louisville is still my favorite choice."
As a junior, Polk, who didn't start playing football until his sophomore season, collected 31 receptions for 762 yards and seven touchdowns.
