Davis was a limited practice participant Wednesday due to a shoulder injury.
In the Jaguars' 47-10 loss to the Bills on Monday, Davis logged 54 of 71 snaps on offense and finished with two catches for 18 yards on six targets. Though he wasn't formally ruled out at any point Monday, Davis likely sustained the shoulder injury at some point along the way, as head coach Doug Pederson told Michael DiRocco of ESPN.com that the receiver is being viewed as day-to-day heading into Sunday's game against the Texans. He'll have two more opportunities to increase his practice participation and put to rest any concerns about his availability this weekend.
