Kubiak confirmed an exchange with Reed but said the Texans wanted to play it safe with the veteran safety.
"I think he was standing there Sunday saying, 'I can give y'all something,'" the coach said Wednesday. "We just, we felt like ... the other decision -- that was the best decision."
But Kubiak doesn't see it that way.
"I don't sense that this is an earmark," Kubiak said. "I think he's been giving us everything he has to come back. ... I see the same driven guy that I've seen the first few weeks.
"It just happens that here, we go to someplace that he's played."
The Texans are more concerned with Reed's long-term viability for the season than his immediate availability. The nine-time Pro Bowler, who turned 35 last week, had arthroscopic surgery in April to repair a torn labrum in his hip.
It was not an injury the Texans anticipated when signing Reed in free agency in March. A report surfaced shortly thereafter that the Ravens knew Reed had a hip issue.
During a conference call with Houston media, Baltimore coach John Harbaugh was asked if the Ravens knew prior to free agency that Reed had a hip problem that could cost him games.
"Well, Ed's had a hip issue for about four years that we've dealt with," Harbaugh replied.
