DAVIE, Fla. -- A daily review of the hot topics coming out of Miami Dolphins training camp:

• It was a semi-light day at Dolphins camp. Miami has its annual team scrimmage at Sun Life Stadium on Saturday. Therefore, Dolphins head coach Joe Philbin gave many of his veterans a light day of work. Veterans such as defensive end Cameron Wake, cornerback Brent Grimes, left tackle Branden Albert, guard Daryn Colledge and safety Louis Delmas dressed but did not take part in team drills and most individual drills. Friday wrapped a physical week of practice where the Dolphins had three sessions in full pads.

• Dolphins backup receiver Rishard Matthews continued his solid week with another strong practice on Friday. Matthews made a series of nice catches in team and one-on-one drills. Matthews received increased reps after Mike Wallace rested this week with a hamstring injury. Matthews is on the roster bubble this summer because the Dolphins are very deep at that position. Matthews is battling with veteran Brandon Gibson and rookie second-round pick Jarvis Landry for the slot-receiver position.

• This was the first practice out of several where the Dolphins didn’t have issues with the snap. Since Tuesday, Miami centers Nate Garner, David Arkin and Shelley Smith all had botched snaps throughout the week. Friday’s practice was clean in that regard. Also, backup center Nate Garner returned to practice from an ankle injury. However, he did not participate in team drills.

• More on the injury front, quarterback Matt Moore hurt his shoulder this week and will miss multiple practices. He will not play in Saturday’s scrimmage. The same goes for rookie receiver Matt Hazel (concussion) and linebacker Tariq Edwards (knee).

• Here is the Dolphins’ weekend schedule: Miami will hold its annual scrimmage Saturday at 9:30 a.m. ET at Sun Life Stadium. Then, the Dolphins will take the day off Sunday. Their first preseason game is Aug. 8 against the Atlanta Falcons.
