SEATTLE — San Francisco 49ers defensive lineman Cassius Marsh was identified Sunday during warmups as throwing Gatorade on a heckling Seahawks fan at CenturyLink Field.

Seattle police spoke with the fan and will write a report in the coming days, according to an officer at the stadium. No other action was taken.

The 49ers are aware a situation involving Marsh occurred, according to a team spokesman. The club will cooperate, if police decide to pursue the issue after the game.

The fan, Rob Larsen, 60, of Seattle, is well-known for his verbal taunts of opposing team players and staff members from his front-row seat near the tunnel that leads to the visiting locker room.

In 2016 while playing for the Seahawks, Marsh was the victim of a car burglary in Seattle. His collection of "Magic: The Gathering" cards, reportedly valued at $20,000 to $25,000, were stolen.

“I always get the scoop on all these players visiting opponents, and I said, ‘Hey, Mr. Marsh, did you ever get your Pokemon cards back?’ ” Larsen told NBC Sports Bay Area. "He didn't like it, and I got doused with a full glass of Gatorade up in the stands."

Larsen, who said he has missed only one game in 16 years, previously filed a civil lawsuit against New York Jets defensive lineman Shaun Ellis for a December 2008 incident in which Ellis was accused of throwing a snowball at Larsen as he exited the field after a game.
