Chiefs outside linebacker Justin Houston was limited in practice Wednesday due to an undisclosed illness.
Other Chiefs who were limited Wednesday were defensive lineman Kendall Reyes (wrist) and outside linebacker Tamba Hali (knee).
Cornerback Phillip Gaines (knee) did not practice. He continues to deal with swelling in his surgically-repaired knee.
Inside linebacker Derrick Johnson is listed on the injury report because the club has not done anything with his roster spot yet. Johnson obviously did not practice Wednesday after he underwent surgery over the weekend to repair his left Achilles, which he tore on Thursday against Oakland. Johnson is expected to be placed on injured reserve at some point.
The Chiefs worked out six linebackers earlier this week: James Laurinaitis, Miles Burris, Jasper Brinkley, Jayson DiManche, Nate Irving and Nick Moody. Moody signed with Washington on Tuesday.
Titans injury report
Tennesee Titans defensive lineman Karl Klug (Achilles) and linebacker Sean Spence (ankle) did not practice Wednesday. Defensive tackle Jurrell Casey (foot) was limited.
Casey has logged 580 defensive snaps with this year, while Spence has logged 435. Klug has logged 389.
The Chiefs and Titans meet at noon Sunday at Arrowhead Stadium.
