Texans wide receiver Andre Johnson returned to practice on Wednesday after sitting out the previous three games with a right hamstring injury.
Coach Gary Kubiak was thrilled to get Johnson back, but remains cautious about his status for Sunday's game against Jacksonville.
"It's a huge step forward," Kubiak said. "It's just good to get him out of working on his own mode and work with the players. I think it's going to be a process this week, but there's obviously a chance (he'll play). It'll be a day-to-day deal."
Kubiak said the team would evaluate Johnson in the coming days to see how his hamstring responds.
"A lot of it with him is him telling me, 'Hey, Kub, I feel fine,' or 'I still feel some tightness there. This, that.' I got to listen to him. He'll let me know," Kubiak said of Johnson's role in the decision. "He's a pro's pro. He'll tell me what's going on."
Fullback James Casey (strained chest muscle) also returned to practice after missing the last two games, and expects Casey to play on Sunday.
"Are we excited to get (Johnson and Casey) back? You bet, because I think it does make us tougher to defend," Kubiak said. "We do have a lot of options and the versatility of James in what we do and knowing how people play Andre, yeah, you want those two guys back on the field. Hopefully, they're back there this week."
