Brandon Marshall exited Thursday night's loss to the Cowboys with a rib injury after he was kneed in the back by safety Barry Church while making a 15-yard reception in the second quarter.
The Bears receiver crouched down after catching the pass from Jay Cutler on fourth-and-seven. Church ran through the receiver, striking him in the right side of his back with his left knee. Marshall remained down on the field for several minutes, clearly in pain.
TV cameras captured Marshall leaving Soldier Field in an ambulance. He later tweeted, "Thanks for the prayers … I'm good." The Bears did not provide an update on Marshall's health after the game.
"It's scary any time that a guy goes down and is laying on the ground," said coach Marc Trestman. "We all worry for him. We'll see, and we're hopeful it's nothing too serious. But at this point he is under evaluation."
Marshall's catch helped sustain a drive that resulted in the Bears' only touchdown over the first three quarters of their 41-28 loss. It came after he had hauled in a 42-yard pass from Cutler with one hand earlier on the possession.
Cutler was worried when his longtime teammate didn't immediately get up after the hit.
"He's a big guy and he has taken a lot of crazy hits over the years," Cutler said. "He doesn't stay down. So whenever he stays down you know something is seriously wrong. We're all worried about him. He's our guy, and hopefully he'll get back sooner rather than later."
Cutler revealed that he spoke to Marshall at halftime, saying: "They were still checking him out, but he was in good spirits."
Marshall exited with three receptions for 61 yards, increasing his season totals to 61 catches for 721 yards. His eight receiving TDs are tied with Alshon Jeffery for the most on the team.
