That is also the main reason Marks was on the field for all but five snaps and Miller played 46 snaps while defensive back Mike Harris played only seven after not playing fewer than 21 in any other game this season. ... Lotulelei made his Jaguars debut. The team claimed him off waivers from Seattle on Oct. 3. ...
