Spiller is expected to miss at least a week, while Reggie Bush could return as early as this Sunday.
For an injury-prone back like Bush, even the smallest of injuries is enough to scare coaches, fans and fantasy football owners alike.
For now they all can breathe a sigh of relief, knowing that the 'Phins feature back won't miss more than a week, if that.
If you're one of the lucky fantasy owners that picked up Bush late in your draft, you'd still be well advised to keep a close eye on the reports from practice as the week progresses.
Based off of what we've seen so far this season, let's hope that Miller steps up and sees the majority of the carries in Reggie's absence.
Miller has racked up 113 yards on 19 carries in two games this season, finding the end zone once while averaging 5.9 yards per carry.
Thomas, on the other hand, has been far less exciting, carrying the ball 22 times for 80 yards in two games while adding a touchdown and a fumble to his resume.
His 3.6 yards per carry isn't bad, but Miller has shown better vision and acceleration to the hole in his chances thus far.
And who knows?
Maybe Jorvorskie Lane will see a few more carries from the fullback position.
At 5'11" and 258 pounds, he should prove to be a solid option all season long in short-yard situations.
It'll be a few more days before we can give an honest assessment of Bush's status this Sunday, but for now, 'Phinatics are thrilled that their star player won't be out for long.
