"Demetress has done really well," Kelly said. "He struggled at first, but he's really starting to pick it up. They feel really confident with him being in there."
Jackson, Jenkins fined
DeSean Jackson and Cullen Jenkins were fined by the NFL for incidents during the Eagles' 24-23 win over the Baltimore Ravens last week, according to a league spokesman.
Jackson was fined $10,000 for unnecessary roughness after the league determined he threw a punch at an opponent during the first half.
Jenkins was fined $7,875 for unnecessary roughness for striking an opponent late.
Three Ravens were penalized, according to the Baltimore Sun.
Ravens running back Ray Rice was fined $7,875 for unnecessary roughness for a late hit. Offensive lineman Marshal Yanda was fined $7,875 for unnecessary roughness that included striking an opponent late, and Cary Williams was fined $10,000 for unnecessary roughness that included grabbing another player by the face mask.
The Eagles departed for Arizona on Friday and will go through their walk-through in Arizona on Saturday, a slight adjustment from a typical trip, when the Eagles leave the day before.
"We tell them to close their eyes on the plane and wake up and pretend it's a new place they're in, and we're on schedule," coach Andy Reid said. "We try to keep the schedules as much as we can the same with the three-hour change."
The Cardinals have six players who are questionable for Sunday after limited participation in Friday's practice: tight end Todd Heap; safeties Adrian Wilson, James Sanders, and Rashad Johnson; guard Adam Snyder; and quarterback John Skelton.
