Cleveland Browns linebacker Barkevious Mingo has been released from hospital after recovering sufficiently from a bruised lung.

Mingo suffered the injury during his side's comprehensive 24-6 pre-season win over the Detroit Lions on Thursday and has been in hospital for the last two nights.

The Browns had initially feared that the 22-year-old rookie would miss their opening match of the season, but defensive coordinator Ray Horton insists that he looks "great", although he refused to put a time scale on his recovery.

"He looks great," Horton told The AP. "As far as projections, the doctors will make that decision.

"We just want him to get healthy and are glad everything is OK. The projection will be whenever his body says he is ready to go."

Mingo was chosen by the Browns as the sixth overall pick in this year's draft.
