Pead did not practice on Tuesday after leaving Monday's training camp session with what appeared to be a hamstring injury, Armando Salguero of the Miami Herald reports.
Without a timetable for a potential return, Pead should be considered day-to-day until further notice. With Jay Ajayi (knee) still sidelined, the bulk of repetitions in the Dolphins backfield will be divvied up between the likes of Kenyan Drake, Damien Williams and Daniel Thomas while the newly-acquired Arian Foster remains limited under a snap count.
