Afterward, Reed downplayed the severity of the injury.
"It was my rib and kidney, I think they said I took a cleat," Reed said. "It felt like I fell on a shoe or something. It's just really sore right now. It hurt like heck when I was out there.
"I just hoped nothing was broken and I didn't feel like anything was broken. It just kind of cut my wind a little bit, but I'll be all right."
Reed didn't appear to have trouble with the torn labrum in his shoulder that he complained of last week and hasn't been listed on the Ravens' official injury report, causing the NFL to look into the matter.
Reed had six tackles against the Texans
Ravens coach John Harbaugh had a similar take on the injury, saying: "It looked like a rib contusion kind of a deal, but I haven't heard the finaly say on that."
