A few Carolina Panthers are about to study under the game's very best. The fifth installment of Tight End University, an annual training summit for the NFL's tight ends, kicked off in Nashville, Tenn.

Tight End University, organized by Kansas City's Travis Kelce, San Francisco's George Kittle and former Chicago Bear Greg Olsen, returns for its fifth year. The summit will take place this week in Nashville, Tenn., where some of the best tight ends in the NFL will get a chance to collaborate and learn from each other.

George Kittle has changed the tight end position for the better with his offseason retreat and this year several Vikings are in attendance.
