WR DeVante Parker (foot) remains question mark for Dolphins

DAVIE, Fla. -- About six weeks before the regular season, the Miami Dolphins remain unsure when 2015 first-round pick and wide receiver DeVante Parker will be ready to return to the field.

Parker had offseason foot surgery on June 5 with the expected timeline to be ready for Miami's Week 1 game against the Washington Redskins. However, Parker hasn't participated in training camp and it is unknown if he will get much -- or any -- work in the preseason.

"It's hard to say; we're not sure exactly when he's going to get back," Dolphins coach Joe Philbin said Tuesday. "I don't know if he's going to practice? How much he's going to practice? If he's going to play in the preseason? Those are all hypotheticals."

Parker has been at the Dolphins' facility every day during training camp working on the side with trainers. Currently, Parker cannot run full speed but is walking fine and doesn't wear a boot. Miami's coaching staff wants Parker to focus on getting mental reps.

The Dolphins selected Parker with the No. 14 overall pick in April with the expectation that he can help Miami's passing game. He looked dynamic in spring practices before the surgery.
