"They are saying four-to-six weeks," Spagnuolo said. "It was six-to-eight last time and he came back a little bit sooner. We'll be optimistic but that's the diagnosis right now and we'll leave it at that."
In seven games this season, Hoomanawanui had 13 catches for 146 yards and three touchdowns — which is tied with wide receiver Danny Amendola in touchdown receptions. Hoomanawanui had two touchdown catches in his last two games.
Spagnuolo said the only other significant injury from Sunday's game was a shoulder sprain suffered by cornerback Justin King.
