Kansas City Chiefs wide receiver Tyreek Hill is under investigation for alleged battery involving his 3-year-old, the Kansas City Star reports.

According to reports, a police report dated Thursday describes a battery incident with a juvenile victim. Listed under “others involved” is Crystal Espinal, Hill’s fiancee. A source told the newspaper that the juvenile in question is Hill’s and Espinal’s son, and the three-year-old ended up with a broken arm as a result.

“The club is aware of the investigation involving Tyreek Hill,” the Chiefs said in a statement. “We’re in the process of gathering information and have been in contact with the league and local authorities. We’ll have no further comment at this time.”

This would not be the first domestic incident involving Hill. Hill was kicked off the Oklahoma State football team stemming from a 2014 incident in which he punched and choked Espinal while she was eight weeks pregnant with the couple’s son, leading to three years of probation.

In three seasons with the Chiefs, Hill compiled 223 receptions for 3,255 yards and 25 receiving touchdowns, adding 63 rushes for 477 yards and four additional TDs on the ground. He’s also scored five career special teams touchdowns on returns. In 2018, Hill generated career highs in receptions (87, 10th-most among receivers in NFL), yards (1,479, 4th-most) and TDs (12, 3rd-most). He has become one of the most prolific wideouts in the NFL.
