SUNDAY, 10:05am: Ian Rapoport of NFL.com tweeted earlier this morning that the Lions were hopeful that Abdullah would return from IR shortly after the team’s Week 10 bye. However, a report from ESPN’s Adam Schefter shortly thereafter indicated that the Lions believe Abdullah has a torn ligament in his left foot and will miss the remainder of the season.
WEDNESDAY, 08:38am: The Lions have placed running back Ameer Abdullah on injured reserve, as Justin Rogers of The Detroit News tweets. The Lions have confirmed the news via press release. 
Abdullah injured his foot on Sunday and it was initially believed to be a sprain. Yesterday, the tailback visited Dr. Robert Anderson in Charlotte and apparently received some bad news. It’s not necessarily known if Abdullah suffered a fracture, but – at minimum – his sprain was more severe than initially thought. Thanks to the league’s new IR rules, Abdullah is not necessarily done for the season, of course. In theory, Abdullah could come back in two months and suit up as soon as Week 11.
With Abdullah out, the Lions will give more carries to Theo Riddick. Of course, Riddick is more of a pass-catching specialist than a workhorse back, so we can expect to see additional work for rookie Dwayne Washington as well. Washington is a bit of an unknown, but coach Jim Caldwell has been talking him up all summer.
The Lions also announced that they have signed running back George Winn and linebacker Zaviar Gooden to the practice squad. To make room, guard Chase Farris and wide receiver Isaac Fruechte have been cut.

Now Zenner will hopefully be the power/goal line back with Theo being the starter and Washington being 3rd down/optional power back
