Detroit Lions rookie running back Ameer Abdullah was one of the biggest winners from the NFL's first week of preseason contests. His cat-like quickness was on display against the New York Jets, especially on his long carry of 45 yards.

While most everyone was impressed with the young ball-carrier's preseason debut, Abdullah was his own biggest critic. In his rookie blog on the Lions' official website, Abdullah wrote that he felt "rusty" during his first game in a Lions uniform.

"I think my first preseason game went OK, borderline good, but by no means great," he wrote on DetroitLions.com. "I missed a lot of holes. I was a little rusty, but that's what I expected getting back into game shape, seeing things at game speed again. There was definitely a lot to learn from. I have a good idea of how the competition will be across the league, what to expect on Sundays and Mondays."

Abdullah was mysteriously limited during Tuesday's practice, according to Kyle Meinke of MLive.com. Lions head coach Jim Caldwell assured that he is not dealing with an injury but would not provide a reason for holding him back.

Meanwhile, fellow Lions running back Joique Bell, who's still on the physically unable to perform (PUP) list, was spotted on the sideline doing sprints. ESPN's Michael Rothstein provided a video of Bell working out on his Instagram account.
