But after going through Friday's indoor practice, both players are expected to participate in the battle for first place.
"They both practiced and they both feel better," Reid said. "They got more work today, and that's a plus. I just want to see how they feel tonight and tomorrow."
"I'm feeling good. I'm pretty excited," said Samuel, who has missed four games this season. "Every day, I'm feeling better. I'm looking forward to tomorrow and the next day."
"You have an MCL sprain, you know what comes from that," Samuel said. "But nobody is 100 percent this time of the year. You just have to deal with it and overcome it. Not being out there and not being able to perform and play with the confidence that you normally would, that gets a little frustrating. But I'm making strides."
Jackson, who rarely lacks confidence -- please see his touchdown reception against the Dallas Cowboys on Sunday night -- also plans to be on the field for what has turned into the biggest game of the season for both teams.
"I still got two days to get ready, so I should be fine," said Jackson, who had 215 receiving yards last week. "At practice today, I did some things. It felt pretty good. I did a lot more today than I did yesterday. I don't think it's that serious to hold me out for a long time. So we should be good and smooth. I'm really not into sitting out games."
Samuel had no choice but to sit out the past three. The Eagles were able to go 2-1 without him, but they allowed 82 points. The pass defense also has fallen from 13th to 17th in the NFL since Samuel's injury.
Right tackle Winston Justice, also questionable, was limited in Friday's practice. He appears like a game-time decision. If Justice can't start, King Dunlap would go in his place.
