Add a starting receiver to the list.

The Vikings announced that Stefon Diggs will be inactive Sunday against the Houston Texans.

Diggs is the latest of four offensive starters to miss at least one start this season. He is out with a groin injury.

Minnesota is already filling in for running back Adrian Peterson, who is recovering from knee surgery, and Matt Kalil (hip), who went on injured reserve the same week as Peterson.

Andre Smith, who started the first four games this season at right tackle, also will be inactive. Smith suffered an elbow injury in Week 4 against the Giants on Monday and was replaced by Jeremiah Sirles, who is likely to start for Smith against the Texans.

The Vikings have opened the season undefeated despite the bevy of injuries that also included quarterback Teddy Bridgewater thanks in part to Shaun Hill (1-0) and Sam Bradford (3-0).

In addition to Diggs and Smith, the Vikings also announced that RB Ronnie Hillman, LB Kentrell Brothers, DT Sharrif Floyd, TE Rhett Ellison and TE David Morgan will be inactive against the Texans.

Here is the full list of inactives:

WR Stefon Diggs
