"Unless something comes up this week where I might tweak it again, that's the only thing I can see holding me back," Couch said. "I'm at 100 percent."
Browns coach Butch Davis prefers to wait until later in the week to make a decision.
"I have no idea," Davis said. "We will find out on Wednesday. The doctors have targeted Wednesday and this week as the week that they think he has a chance to be the starter. He's done religiously what our medical people have asked him to do.
"We're all moving forward with the idea that he'll be able to do it. As I've said every day for the last three weeks, every day he goes out to throw is self-revealing. We find out he's getting closer and there's no soreness. He took no negative steps in the last two weeks. All indications are that he's moving in that direction (to start)."
Kelly Holcomb has played well in Couch's absence. He's completed 44 of 69 passes for 524 yards, five touchdowns and no interceptions.
Holcomb said from the time he was named the starter for week one that the Browns are Couch's team. He prepares himself to start each week, although he knows that Couch will get the call when he's cleared to play.
"Kelly has played well, but Tim is the starting quarterback," Davis said. "If Tim is well enough to play and be the starting quarterback, he'll be the starting quarterback. Kelly will do exactly what he's been doing, and that's to prepare to win."
If Couch starts, he knows that he'll face a tall order against the Titans. If he doesn't play well, he's prepared to take the heat.
"I know every time I throw a bad pass that they're going to be booing and wanting Kelly in," Couch said. "That's part of life in the NFL. The backup quarterback is always the most-popular player on the team.
"I've been dealing with that for four years, and it's no big deal for me. I really don't care what they think, to be honest. As long as we're winning football games and I'm doing what I think I should be doing … every one has an opinion and is allowed to talk and say what they want to say."
GETTING THERE: Offensive tackle Ryan Tucker, who sat out last Sunday's game with a slight tear of ligaments in his left knee, expects to play Sunday.
"It's going well," Tucker said. "I ran hard on it today (Monday). The true test probably won't come until Wednesday. I'm going to come in Tuesday and put pads on and see how it feels. I'm going to play a game pretty much on Wednesday to see how it holds up."
NOT EASY: Davis admitted that he faced a tough challenge in preparing the players to put the 40-39 loss to Kansas City behind them.
"I've had a lot of them (tough losses)," Davis said. "Maybe more than you deserve. Whether it was 'Hail Flutie' in 1984 or whenever that was. There have been bleak game days. All I know is that players take their key from the coaching staff. If they moan about it, and if I'm in a funk all week long, the players are going to be in a funk. None of that will help us win a game."
GAME BALLS: Chris Akins and kicker Phil Dawson were honored for their play on special teams. Defensive honors went to Mark Word, linebacker Brant Boyer and strong safety Robert Griffith. Receiving balls on offense were tackle Ross Verba, who graded out to 92 percent, tackle Roger Chanoine and quarterback Kelly Holcomb.
