Gardner (calf) won't practice Wednesday, Mike Chappell of FOX 59/CBS 4 Sports reports.
Gardner hasn't practiced or played since sustaining a calf injury Nov. 30 against the Texans. The Colts placed fellow starting cornerback Charvarius Ward (concussion) on injured reserve Wednesday, so they will be significantly depleted in the secondary against Jaxon Smith-Njigba and the Seahawks if Gardner isn't available Sunday.
