Miami Dolphins' Mike Wallace practice absence not serious

Miami Dolphins wide receiver Mike Wallace has revealed that he is battling a groin injury as he looks to be fit to face the Dallas Cowboys on Sunday.

The 27-year-old missed the Dolphins' practice session on Tuesday but admitted that problem is not serious and that he hopes to be fit for their pre-season opener in the Hall of Fame game.

"It feels pretty good," Wallace told the Miami Herald. "I feel like it's getting there."

Wallace joined Joe Philbin's side earlier this year on a five-year deal.
