One week into mandatory minicamp, the New England Patriots saw two of their biggest offensive weapons take the field for the first time today. 

Both tight end Rob Gronkowski, who was held out of practices for an undisclosed reason last week, and running back Dion Lewis, who suffered an ACL tear last season, made their first appearances of the offseason during today's workout.

According to a ProFootballTalk.com report, Gronk declined to specify what exactly held him out of last week's drills. The big tight end did say "it felt great" to be back on the field with his teammates, according to a Patriots.com report.

Lewis, who made his first real test of his surgically repaired ankle, mainly participating in individual position drills, said he felt "a little rusty."

Although he was not involved fully in every part of practice, it was an important step in his progression.

Having both Gronk and Lewis back on the field and ready to go for the regular season will be key for the team's game plan.
