Attorney Todd Hollis gave a picture to KDKA-TV of his client, De Vincent Spriggs. The picture shows Spriggs with a swollen right eye. Hollis told the station the incident occurred between April 10 and 11 in Pittsburgh. Hollis said Spriggs would be filing the criminal charges against the star NFL player.

The Rams selected Donald with the No. 13 pick of the 2014 draft, and he was instantly a high-caliber defensive player. In his rookie season, he recorded nine sacks and 48 tackles. Since then, he’s been a three-time Defensive Player of the Year and a six-time All-Pro selection.

He’s played in 16 games for three straight seasons. In 2020, he recorded 13.5 sacks, 45 tackles and four forced fumbles.

The team said it was "collecting more information" about the alleged assault.
