The Browns will be licking their wounds for a while after being hit with a rash of injuries during their 24-6 win over the Detroit Lions in the second preseason game Thursday night.

Rookie outside linebacker Barkevious Mingo spent a second night in the hospital with a bruised lung and was released Saturday morning a team spokesman said. Running back Dion Lewis will undergo surgery on a fractured left fibula and right guard Jason Pinkston could miss the early part of the regular season with a right high ankle sprain coach Rob Chudzinski said Friday during a conference call.

Mingo is expected to be out for at least a week or two a league source told the Beacon Journal speaking on condition of anonymity because of the sensitive nature of the situation.

Chudzinski did not give a timetable for Mingo’s return. He said the Browns haven’t been able to identify a specific play during which Mingo was hurt.

“He felt better this morning” Chudzinski said of Mingo the sixth overall pick in this year’s draft. “He stayed overnight in the hospital. We’re going to keep him over another night as a precautionary measure. It’s a little bit too early to give you any estimates on where that stands.

“He has a bruised lung. So anytime that there’s that kind of injury they just want to make sure everything’s OK in terms of his health and breathing and everything else.”

The Browns will visit the Indianapolis Colts on Aug. 24 in their third preseason game. Mingo will sit out then and possibly miss the preseason finale Aug. 29 against the Chicago Bears.

The Browns will open the regular season at home Sept. 8 against the Miami Dolphins. Although Mingo is their backup right outside linebacker the Browns are counting on him to be a key part of their rotation of edge rushers this year.

Lewis is one player who definitely won’t be available for the opener and he could be out all season. He’ll need surgery after breaking his leg with 7:52 left in the third quarter when he caught a pass from quarterback Jason Campbell for 6 yards and was tackled by linebackers Travis Lewis and Ashlee Palmer. Chudzinski said the procedure has yet to be scheduled.

“Thanks for all of the prayers” Lewis tweeted Friday.

The Browns could place Lewis on season-ending injured reserve or they could put him on IR and designate him to return after Week 8 of the regular season. Chudzinski said the organization will wait until roster cuts are executed at the end of the month to make a decision.

“We don’t have to make these decisions until the final roster is put together” Chudzinski said. “At that time you can figure out who is going [on which list].

“[Lewis] was one of the guys that had had an opportunity to show what he could do. [He was] really catching our eye.”
