Steelers placed LB Robert Spillane on injured reserve with a knee injury.
Pittsburgh’s defense will be without Spillane, who replaced the injured Devin Bush (torn ACL), until at least Week 17. Spillane went down in Week 13. Already without Bud Dupree (knee) for the rest of the season, the Steelers’ linebacker group has been decimated by injuries. LB Avery Williamson, acquired just before the trade deadline, is the next man up. Opposing tight ends might have an easier time against the Steelers in the coming weeks. Logan Thomas roasted the Steelers on Monday, catching nine balls for 98 yards and a score.
