The Cardinals are facing the Baltimore Ravens this week, who are allowing the third-fewest rushing yards in the league, so even if Wells were at full strength, this would be a tough matchup. The guy who will get the carries Wells can't handle will likely be speedster LaRod Stephens-Howling. In other weeks, he'd be a starting option, but against the Ravens, you should really consider other options.
If Wells is a full go, he might get a touchdown. He's been, shockingly, a very reliable fantasy performer when healthy, but his recent streak of game-time decision injuries has been frustrating for owners and fantasy writers alike. We feel your pain.
