The players may be on "vacation" until training camp begins at the end of July, but the Detroit Lions' front office certainly isn't. The Lions are still fine-tuning their roster in preparation for training camp, and they made a change to it on Thursday night by signing long snapper Matt Camilli and releasing offensive guard Pat Boyle.

Lions have signed long snapper Matt Camilli (UTEP). Released G Pat Boyle to make room on the roster. Camilli worked out for the team Thurs.

Camilli was signed by the Philadelphia Eagles this year as an undrafted free agent. Interestingly enough, the Eagles released him last week in order to make room on their roster for one-time Lions free-agent target Oshiomogho Atogwe.

In all likelihood, the sole purpose of this signing is to give Don Muhlbach a bit of a break during camp. By having a second long snapper on the team, Muhlbach won't have to take all of the reps as the long snapper for field goals and punts.
