Kight (knee) was placed on IR on Tuesday, John Boyle of the Seahawks' official site reports.
The rookie offensive lineman from UCF joined Seattle's active roster late in the season with both Charles Cross and Josh Jones dealing with injuries. However, Kight won't be able to suit up for a Super Bowl LX matchup against the Patriots. Expect Jones and Mason Richman to operate as the Seahawks' top reserve tackles.
