BEREA -- Browns quarterback Jake Delhomme wore a walking boot on his right ankle and didn't practice Wednesday, but remained hopeful he would be able to play Sunday against Kansas City in the home opener.
"I'm always optimistic about anything," he said Wednesday. "We're just going to be aggressive in our treatment and see where that takes you."
Coach Eric Mangini wouldn't go into details about the injury, but categorized it as day to day. He said he'd make a decision at the end of the week about his availability.
If Delhomme can't go, career backup Seneca Wallace would start. He's 5-9 as a starter in his career with 25 touchdowns and 14 interceptions.
"I have tremendous faith in Seneca," Mangini said.
The timing of the injury is rough for Delhomme. He's new to the Browns and threw two interceptions Sunday in the opening loss to Tampa Bay.
"It's extremely disappointing," he said. "It's embarrassing to me. That's just kind of the way I am. I believe you should be out there with your guys."
Delhomme hurt his ankle on the game-changing interception in the first half Sunday. He got the ankle taped at halftime and played the whole second half, but hobbled after a number of plays.
He went 9-for-19 for 121 yards in the second half with an interception, and the Browns didn't score. He said he didn't regret staying in the game.
"Not at all," Delhomme said. "If I felt I was going to be a detriment to the offense in the second half, I feel I would be smarter than that knowing we have an extremely good quarterback also in Seneca."
** Nose tackle Shaun Rogers (leg) and rookie offensive lineman Shawn Lauvao (ankle) also didn't practice. Mangini said Rogers is expected to return later this week.
Linebacker D'Qwell Jackson (pectoral) is on schedule to practice Friday. He missed all of the preseason and has been out since Aug. 10.
