The Rams will place CB Al Harris and TE Mike Hoomanawanui on injured reserve with torn ACLs, head coach Steve Spagnuolo confirmed on Monday.
Both players suffered the injuries in Sunday's win over the Browns. Harris will be the ninth cornerback the Rams have placed on I.R. this season, joining Week One starters Ron Bartell and Bradley Fletcher.
The four corners left on the Rams' active roster are Justin King, Josh Gordy, Marquis Johnson and Rod Hood.
Harris, 36, is in his 14th season. He started five games in 2011 and had seven passes defensed.
Hoomanawanui, a second-year pro, had seven catches for 83 yards this season. He started all eight games he played in.
