"There was added swelling in his leg," Ryan said, "but hopefully he'll be ready to roll."
"As of right now, we're going to take it day by day, like we've been doing, and see how it goes," Revis told the New York Daily News after the game.
"This process is kind of frustrating, because I've never been hurt during the season," Revis added. "I want to be out there so bad with my teammates and win games. I need to learn patience right now and get back to 100 percent. ... When that happens, I can play the type of ball that I can play."
Ryan said he was unaware that Revis' hamstring was a problem during the game.
"I thought just the opposite," Ryan said. "I thought about challenging him more. I never saw it."
Ryan added that he hadn't spoken to Revis as of early Tuesday afternoon. Ryan also said the team wouldn't rest Revis this week just because its bye is the following week, giving the cornerback more time to recover.
"If he's healthy, we want to play Darrelle," Ryan said. "It's not vacation time. It's time to beat somebody. This is an AFC opponent and we need to win games so we can get into the postseason. That would be my thought. Is he going to be better three weeks from now if we don't play him or all that? I think that still has to be determined."
Ryan insisted that the team didn't rush Revis back and said the wet conditions during the game played no factor in the decision to let him play.
"We wouldn't have put him out there if we didn't think he was healthy," Ryan said. "We thought he was healthy, ready to play. I think he felt he was healthy, ready to play."
"For the standards of Darrelle Revis, let's face it, we expect him to go out, and if this was golf, we expect him to birdie every hole," Ryan said. "That's the truth. Now, if he has a couple of par and a bogey every now and then, what's wrong with Revis, you know what I mean? But hopefully, this injury is not that big a deal."
