The UFL is investigating an incident involving Michigan Panthers wide receiver Samson Nacua, who appeared to slap a fan after Saturday night’s game against the host St. Louis Battlehawks.

“The UFL is aware of the incident that took place last evening at the conclusion of the Michigan Panthers vs. St. Louis Battlehawks game in St. Louis. League officials are currently investigating the matter,” the UFL said in a statement on Sunday.

The 27-year-old Nacua, whose younger brother Puka Nacua is a star receiver for the Los Angeles Rams, is seen on video lunging toward, and making contact with, a spectator who is leaning over the railing. The fan was apparently heckling Samson Nacua after the Battlehawks defeated the Panthers 32-27.

Audio from the video also appears to capture the sound of Nacua making contact with the fan.

Nacua made three catches for 46 yards in the game. In five games, he has seven receptions for 116 yards and one touchdown. The Panthers (3-2) are tied for first in their division with the Birmingham Stallions.

Nacua played four seasons at Utah and one at BYU, finishing with 1,344 yards and 14 touchdowns on 103 catches in his career.
