The Jets placed Fotu (hamstring) on injured reserve, designated to retun Tuesday, Ethan Greenberg of the team's official site reports.
Fotu played in New York's first preseason contest but subsequently injured his hamstring. There was initially optimism that he'd be ready to return by the start of the regular season, but his placement on IR means the 26-year-old will be forced to miss at least New York's first four games of the campaign. Fotu is likely to play a rotational role on the Jets' defensive line upon his return.
