Tucker has missed the last two games with an undisclosed illness and Holly missed last Sunday's game also with an undisclosed illness.
"Tucker is back," Romeo Crennel said. "We'll work him in and see how he is and if he can help us."
Crennel wouldn't give any indication of what was wrong with Tucker.
"It was an undisclosed illness and he'd rather leave it like that," Crennel said.
Nor would Tucker.
"It's irrelevant, now," Tucker said. "I feel good. I needed time to recover, but the bottom line is I'm here.
"I'm excited to be back," he said. "It's been a day-to-day thing. I was sick before the last game I played and battled through it."
Tucker was asked if he would play Sunday and beyond.
"I'll be out there and be right where I left off," he said. "It's been tough to be out. I expect to be ready for the rest of the season, God willing."
Crennel was asked if he thought Tucker was in condition.
"I'm not sure what he was doing since he wasn't here," Crennel said. "Generally, these guys don't get too much out of condition.
"He's an experienced veteran who gives the other players confidence."
Tucker missed the last two games. He last played against the Broncos on Oct.
22. He must be feeling pretty well as he was displaying pictures in the locker

"I'm feeling pretty well and ready to go," Holly said.
Crennel said Holly had been making good strides before being sidelined.
"He's handling his role pretty well before he had this illness," Crennel said. "He's understanding the secondary and what he has to do. If he can return that should help us."
Holly is in his second season out of
Test for Charlie: Crennel said he is looking to see the development of QB Charlie Frye in the second half of the season.
"Every game is important for him to improve and get better," Crennel said. "I would like to see improvement, in general. If he can improve the turnover ratio that would be good."
"I'm looking forward to the second half of the season," he said. "I would like to improve and most importantly, get some wins."
He was asked what areas he needs to work on.
"Obviously, I have taken too many sacks and I have to do a better job of getting out of bounds," he said. "The turnover ratio is important to win games."
There has been speculation that Frye has been locking on to a receiver and allowing defensive backs to prey on his passes.
"He locked on a wide receiver a couple of times and we're going to work with him and help him improve," Crennel said.
"I've seen that in the films a little and I'm working on that," he said. "I think with a little experience that will get better."
Crennel is confident that Frye will get better.
"He's a competitor and he's going to work to try to get better."
Frye said he understands the criticism that is put at the feet of the quarterback.
"Quarterback is a tough position to play," he said. "If I didn't want (the criticism) I would've played golf or something else.
"It's the nature of the game and the position."
Tucker is back. Work him in and see how he is and if he can help us.
Undisclosed illness he'd rather leave it like that. Not sure what he was doing since he wasn't here. Generally, these guys don't get too much out of condition.
Crennel said he was in contact with Tucker while he was out. He's an experienced veteran who gives the players confidence.
Minter to Practice: Crennel said CB Demario Minter has been cleared to practice and the Browns will look at this year's fifth-round draft choice to see if he can help this year's team. Minter had knee surgery prior to training camp and has been on the Physically Unable to Perform (PUP) list.
"We have three weeks to see if he can help us and then decide whether to activate him or not," Crennel said. "We'll take the same look as we would other players and see what he can do. If he can play, we might be inclined to use him sooner than later."
Bodden Doubtful: Crennel said CB Leigh Bodden (ankle) is doubtful for Sunday's game with the Falcons. Also, many other players are still questionable: LB Willie McGinest (ankle), LB Leon Williams (ankle), OL Joe Andruzzi (knee), OL Kelly Butler (wrist), OL Cosey Coleman (knee), QB Charlie Frye (thumb), CB Daven Holly (illness), WR Joe Jurevicius (back), CB Demario Minter (knee), WR Dennis Northcutt (ribs), CB Jereme Perry (ankle), DL Orpheus Roye (hamstring), LB Matt Stewart (head), OL Ryan Tucker (illness) and TE Kellen Winslow (knee).
Crennel did say he was hopeful most of the players listed will play.
