The Jaguars' didn't get the news they hoped Friday.

Marcedes Lewis, the Jaguars' Pro Bowl tight end and a player critical to the running and passing offense, practiced on a limited basis Friday morning, and has been listed as doubtful on the team's injury report for Sunday's game against the New York Jets.

Lewis, who sustained a calf strain against the Tennessee Titans in the regular-season opener, was one of two players listed as doubtful, with the other being wide receiver Jason Hill. Jaguars Head Coach Jack Del Rio said each was "very, very limited" Friday.

Defensive end Aaron Kampman and cornerback Derek Cox have been ruled out.

Lewis, a Pro Bowl selection last season, likely will be replaced in the lineup by Zach Miller, who practiced all three days this week after missing the regular-season opener with a knee injury.

"He's a Pro Bowl player," Jaguars Head Coach Jack Del Rio said about Lewis Friday as the Jaguars (1-0) prepared to play the Jets (1-0) at MetLife Stadium in East Rutherford, N.J., Sunday at 1 p.m.

"We're prepared to plug in as you do as a football team. The next guy gets an opportunity to step up and we continue to play well as a football team."

Miller said Friday he expects to play after returning to practice full the entire week.

"I practiced all week and ran around like I'm supposed to," Miller said.

With Hill – who sustained a hip flexor injury against Tennessee – possibly out, rookie wide receiver Cecil Shorts could get his first NFL start. A third-round selection, Shorts played extensively in the opener although he did not catch a pass.

"I'm looking forward to playing," Shorts said. "Of course, we want Jason to be out there, but if he can't go, me and (rookie free agent Jamar) Newsome and the guys – we'll all be ready to go. When the opportunity arises, you have to take advantage of it."

Shorts, like other Jaguars rookies, has been with the team only about six weeks. He said while the adjustment process was a quick one, "I'm happy with my development."

"I'm getting the plays down, and once you get the plays down, you can go out there and start playing," Shorts said. "The more you play, the more experience you get, and that's when you start getting more savvy."

Del Rio said of Shorts, "He's done a nice job of learning our system and becoming a guy we have gained confidence in. He understands where he belongs and has good hands. He's a good player and he likely will get more opportunities if in fact Jason is not able to go."
