Before the Dolphins took a chance on the aging, oft-injured Arian Foster this summer, they were set to the enter the season with a bunch of no-names forming the saddest backfield in the NFL. Unfortunately, because Foster ended up coming aboard and winning the starting job, we'll never get to know how the season would've played out for the Dolphins with a backfield headed by Jay Ajayi.

For one week at least, we'll get a sense of what could've been. Because, this Sunday, Foster will not play due to a groin injury. There is no timetable for his return, with Dolphins coach Adam Gase saying that he'll be re-evaluated next week.

Gase also claimed he has no idea who he'll start.

So, the obvious candidate is Ajayi, who was set to be the starter before Foster showed up. However, since then, he's been on a slide. He didn't travel to the Dolphins' Week 1 game against the Seahawks, with Gase opting to leave him behind in Miami for undisclosed reasons. In the Dolphins' second game, Ajayi carried the ball five times for 14 yards.

Next up on the depth chart is Damien Williams. He's carried the ball twice for nine yards this season. Behind him are Kenyan Drake (two carries for 12 yards) and Isaiah Pead (no carries yet). So, clearly, Gase's options are limited.

Still, he's not concerned, even though the Dolphins' running game ranks 27th in the league. At least that's what he told reporters.

"I'm all right with where we are at right now," Gase said, per The Miami Herald. "I know why certain things are what they are, and you'll know if I have a concern with the running game."

The good news for the Dolphins is that their leading rusher on the season is still healthy. The bad news for the Dolphins is that their leading rusher is quarterback Ryan Tannehill, who leads the team with a grand total of 52 yards.

The point being, if you're down Foster in Fantasy, it might be best to simply ignore the Dolphins' backfield until he returns. Tannehill doesn't even play running back, Ajayi certainly doesn't look like a workhorse, and the rest of the backfield hasn't done much of anything either.

So, this is one of those rare times you might want to avoid the Browns' defense for Fantasy purposes. Get all the Week 3 injury Fantasy analysis you could need here.
