Lewis added to uncertain list for Sunday

The Jaguars are now dealing with another player who may not be available for Sunday’s season opener.

Tight end Marcedes Lewis missed practice on Thursday, one day after reinjuring his left calf -- an injury he suffered in pregame warmups against the New York Jets on Aug. 17. That means coach Gus Bradley isn’t sure if he’s going to have his starting quarterback and tight end against Kansas City.

"We’ll continue to evaluate [Lewis], see where he’s at," Bradley said. "I know that he was riding the bike and going through some of the rehab things for his calf with [head athletic trainer] Mike [Ryan]."

Bradley said the plan is to be cautious with Lewis, who is coming off a 52-catch season, to keep the injury from becoming a long-term issue. Lewis will be re-evaluated on Friday.

"We don’t want to put him in there and have this continue to be another three weeks," Bradley said.

Lewis has been limited in practice since he suffered the original injury. If he can’t play, the Jaguars will have to rely on Allen Reisner, who signed with Minnesota as an undrafted free agent out of Iowa and spent 2011 and most of the 2012 season on the Vikings’ practice squad, and two tight ends they claimed off waivers on Saturday.

Clay Harbor spent the past three seasons with Philadelphia and caught 47 passes for 421 yards and four touchdowns. D.J. Williams played in 26 games over the past two seasons with Green Bay and has nine receptions for 70 yards.

Bradley said he’s still unsure if Gabbert will be able to play against the Chiefs, but he is pleased with the progress Gabbert has made from the fractured right thumb he suffered against the Jets. Bradley said Gabbert was limited in practice on Thursday but took more reps than he did on Wednesday.

"If it was a situation where we felt like Blaine couldn’t make the throws we want him to make then the decision would be made right now," Bradley said. "But right now we’re seeing him make some of the throws. We’re seeing him do a lot of things we’re asking him to do. Now, we’ll go through it one more time tomorrow and finalize it."

Chad Henne and Ricky Stanzi got extra reps just in case, Bradley said.
