The Arizona Cardinals will be as healthy as they've been all season with four players who missed their last game returning to practice Tuesday.

Wide receiver John Brown, tight end Darren Fells, outside linebacker Alex Okafor and cornerback Jerraud Powers are expected back in the lineup for Sunday's division showdown at the Seattle Seahawks.

Okafor has missed the past three games with a calf injury and Fells (shoulder) sat out the last two. Brown and Powers were held out of the Week 8 win at Cleveland with sore hamstrings even though both players were active for the game.

The only player missing Tuesday's practice was center Lyle Sendlein, who may not be available Sunday because of a shoulder issue. Cardinals coach Bruce Arians did not rule out Sendlein but said that backup center A.Q. Shipley will "probably" start against Seattle, which trails Arizona by two games in the NFC West.

"There's always a chance with him," Arians said of Sendlein. "I've seen him play through it before, but I'd rather have a full speed guy than an 80-percent-hurt guy."

Okafor could provide a boost to a pass rush that ranks among the bottom six in the league with 13 sacks. Okafor registered a team-high eight sacks last season and is tied for the team lead with two despite missing the three games.
