BEREA, Ohio -- Browns rookie linebacker Barkevious Mingo did some running Tuesday, a few steps forward in his recovery from a bruised lung.
Mingo believes he sustained the unusual injury in an exhibition game on Aug. 15 against Detroit. Browns coach Rob Chudzinski said Mingo, who has been doing his conditioning by riding a stationary bike, was going to "run a little bit." Mingo did not do any running during the portion of practice open to the media.
A team spokesman confirmed that the first-round draft did some running, but did not provide any specifics.
Mingo will not play in Thursday's exhibition finale against Chicago and it's not yet known if the No. 6 overall pick will play in the Sept. 8 season opener against Miami. Chudzinski reiterated that it's still to be determined when Mingo will return.
"We have no timetable," he said. "We will just have to see how he progresses and how he heals. It's really just an individual thing, from individual to individual, on how they heal."
Chudzinski said the Browns have ruled out placing Mingo on the short-term injured reserve list, which would sideline him for half the season.
The last time he spoke with reporters, Mingo said he was following doctor's orders and would not rush back.
The 6-foot-4, 240-pounder said he spit up some blood during the first half of the game against the Lions and later at the hospital. He was kept for two nights at The Cleveland Clinic.
