Brandon Marshall out of hospital

LAKE FOREST, Ill. -- Chicago Bears wide receiver Brandon Marshall, who was discharged from Northwestern Memorial Hospital on Monday, has been placed on the reserve/injured list.

To replace Marshall on the roster, the Bears elevated receiver Josh Bellamy to the 53-man roster from the practice squad. They also signed linebacker Jonathan Brown to the practice squad.

Marshall spent three days in the hospital receiving treatment for a collapsed lung he suffered following a 15-yard reception in the second quarter of the Bears' 41-28 loss to the Dallas Cowboys on Thursday night. Marshall also fractured two ribs on the play when Cowboys safety Barry Church kneed the receiver in the back.

"It was really scary," Marshall told ESPN 1000's "Waddle and Silvy" Show on Monday. "I'm one of those guys that when I hit the ground I try and get up right away. I don't care how tough it is. But as soon as he hit me, I thought this may be one of those situations where they could be some internal bleeding. But that wasn't the case. I just had a few [fractured ribs] and a collapsed lung."

He finishes with 61 receptions for 721 yards, his lowest outputs since the five-time Pro Bowler's rookie season in 2006 while a member of the Denver Broncos. Marshall caught 218 passes for 2,803 yards and 23 touchdowns over his first two seasons in Chicago, and he signed a three-year extension in the offseason. He has dealt with chronic ankle problems for most of the year that limited his effectiveness.

Bellamy has appeared in nine games over three seasons with Kansas City (2012), Washington (2013) and Chicago (2014), appearing mostly on special teams. He also spent time on San Diego's practice squad in 2013 and Kansas City's in 2012. Brown entered the NFL this season as an undrafted free agent out of Illinois.
