"It feels better," Ellerbe said. "It's a whole lot better from Saturday."
Ellerbe said he felt the knee was at about 60 percent, which may be enough to get him on the field Saturday.
"Chances to me, right now, I'm getting better, so I'd say it's more than a 50-50 chance," he said.
Ellerbe will need to participate in at least one practice this week, he said, to be cleared to play. If he is active for the game, however, he likely won't fill his usual role on kickoff and punt teams.
"Hopefully it'll be more than 15 or 20 plays, but I know it'll strictly be defense, probably no special teams," Ellerbe said.
