Thirty-one-year-old Todd Kobus, of Attleboro, made an initial court appearance Monday in Wrentham District Court, where a pretrial hearing was set for Feb. 17.
The Patriots said the fan was removed from the stadium and arrested by police after Seau was tackled during the fourth quarter of Sunday's game.
Seau, a 12-time Pro Bowler, had sat out the season before rejoining New England for its game at Seattle on Dec. 7. He was their leading tackler Sunday in his third game with the team this season.
