Ameer Abdullah can't explain it. After starting the first 11 games of the season at running back, Abdullah has barely played the last three weeks. Some of it is due to health. He hurt his neck in the Detroit Lions' Thanksgiving loss to the Minnesota Vikings, and missed the next game because of the injury. But in Saturday's win over the Chicago Bears, Abdullah played just eight snaps and spent the majority of the second half on the bench even after newly-minted starter Theo Riddick got hurt. "It's definitely frustrating," Abdullah told the Free Press on Monday. "It’s definitely something that I just want to take in and do my best to grow from it. That’s it." Abdullah said he hasn't been given an explanation for why he lost his starting job, though he admitted last week that he hasn't played up to his standards this year. In his first 11 games, Abdullah ran for just 505 yards, and he's averaging a career-worst 3.4 yards per carry on the season. The Lions rank 31st in the league in rushing offense at 77.4 yards per game. "That’s something you’ll get better answers from Coach," Abdullah said. "I don’t really have any answers for you." Lions coach Jim Caldwell refused to admit the obvious after Saturday's game that Abdullah had been benched.
