Commissioner Roger Goodell was at the Browns' facility Thursday to visit with players and the media. It took reporters less than two and a half minutes to start asking about Michael Vick.
Goodell said it is "despicable" and "incomprehensible" to think anyone would be involved in dog fighting, "much less an NFL player being charged in some way."
Goodell said the NFL will probably make a decision on the fate of the Falcons quarterback in the next week to 10 days.
Vick is charged with running a dog-fighting ring on property he owns in Virginia. Dogs that lost or were weak were executed in grisly ways - electrocution, drowning and hanging.
A former co-defendant in the case, Tony Taylor, said in a plea agreement that Vick financed the "BadNews Kennels" dog fighting operation. His statement linked Vick to gambling.
NFL policy strictly prohibits players from gambling and associating with gamblers. A player could be banned for life for violating the policy.
"The gambling is certainly an issue," Goodell said. "Law enforcement may be concerned about certain things. We may be concerned about other aspects of this. That's why we want to evaluate what the government has.
"We don't know all the facts on that. Michael's team may not know all the facts at this point in time."
Goodell banned Vick from the Falcons training camp as the investigation continues.
