On the same day that rookie receiver Jared Abbrederis learned that his season was over because of a knee injury, the Green Bay Packers had two other injury scares during their annual Family Night event at Lambeau Field.

One of them, to rookie tight end Colt Lyerla, was potentially serious.

On the other, to veteran nose tackle B.J. Raji, the Packers appear to have gotten lucky.

Packers coach Mike McCarthy decided not to scrimmage on Family Night, but rather just hold a regular training camp practice. There is no live tackling in McCarthy's practices.

Lyerla wouldn't specify his exact injury, but he had crutches in his locker. He would only call it a leg injury and when he was not using the crutches, he walked slowly and with a limp. The injury occurred on one of Lyerla's biggest -- and perhaps most unwise -- plays of training camp.

After he caught a pass from Matt Flynn, Lyerla hurdled cornerback Jumal Rolle and got drilled by cornerback Jarrett Bush before he hit the ground.

"I was just trying to make a play," Lyerla said.

Perhaps he felt he the need to do so after a slow start in his return to football after leaving the University of Oregon midway through last season.
