Cleveland Browns rookie linebacker Barkevious Mingo is unlikely to play in the team's regular-season opener against the Miami Dolphins on Sept. 8 because of his bruised lung, a league source told ESPN NFL Insider Adam Schefter.
The Browns, however, believe Mingo, the sixth overall pick in April's NFL draft, should be able to return in Week 2 against the Baltimore Ravens.
The Browns have scheduled a CT scan for Mingo on Monday, a league source told ESPN NFL Insider Ed Werder. The test should help the team make a determination on his status for Week 1.
The Browns said Mingo worked out with weights Wednesday. He hasn't practiced since bruising his lung Aug. 15 against Detroit and being hospitalized for two days.
The 6-foot-4, 240-pound Mingo has said he spat up blood on the sideline and experienced shortness of breath during the game against the Lions. He believes the injury occurred on the opening kick.
Mingo did some running Tuesday, when coach Rob Chudzinski said there was no timetable on the linebacker's return.
Chudzinski said the Browns have ruled out placing Mingo on the short-term injured reserve list, which would sideline him for half the season.
