Kansas City Chiefs linebacker Justin Houston was activated from the physically unable to perform (PUP) list on Wednesday, the team announced.

Houston underwent surgery to repair his ACL in February and was placed on the PUP list in August, ruling him out of the team's first six games.

The pass rusher was a limited participant in Wednesday's practice and it's unclear when he'll be able to make his season debut.

Kansas City faces off against the Carolina Panthers on Sunday.

Houston was named to the Pro Bowl in four consecutive seasons (2012-15) and led the NFL in sacks during the 2014 campaign.
