JACKSONVILLE – J-Rob is questionable entering the weekend again.
"James is day-to-day," Head Coach Urban Meyer said Friday as the Jaguars (2-7) prepared to play the San Francisco 49ers (4-5) at TIAA Bank Field in Jacksonville Sunday at 1 p.m. "We're just being real cautious with him. He's feeling pretty good."
Robinson, who has rushed for 539 yards with six touchdowns on 100 carries this season, also has 22 receptions for 160 yards. He sustained a heel injury against the Seattle Seahawks on October 31, missed a victory over Buffalo the following week and rushed for 57 yards on 12 carries with four receptions for 27 yards in a loss to Indianapolis this past Sunday.
He was listed as questionable entering the Indianapolis game, and is listed this week with a heel/knee injury.
"The trainers came up to me and told me that after the game – or this week – he was just getting treatment on his knee," Meyer said.
Meyer on Friday also called center Brandon Linder (ankle/knee) and tight end James O'Shaughnessy (ankle) "day to day." Both players were designated eligible to return from injured reserve this week, and must be moved to the active roster before playing.
Tyler Shatley has started at center since Linder's Week 5 injury against the Tennessee Titans. The Jaguars have played with three active tight ends in recent weeks – Dan Arnold, Chris Manhertz and Luke Farrell. Meyer on Friday said it's possible to have four tight ends active, though special teams must be considered in that scenario.
"He's actually looking pretty good in practice; that's the O'Shag I remember before he got hurt," Meyer said. "He (O'Shaughnessy) became a much better blocker before his injury. I've always felt he's a good, quality receiver."
Linebacker Myles Jack (knee) participated full in the walkthrough Friday; he missed practice Wednesday and Thursday. Jack started against Indianapolis Sunday after missing practice on Wednesday and Thursday. "He's good," Meyer said. Linebacker Dakota Allen (shoulder) practiced limited Friday and was ruled out of Sunday's game. All other Jaguars players on the injury report this week – safety Rayshawn Jenkins (illness), punter Logan Cooke (left knee), running back Carlos Hyde (shoulder) defensive tackle Malcom Brown (rest/toe) and defensive end/linebacker Jordan Smith (illness) – are expected to be available Sunday.
The Jaguars' defense, after allowing at least 368 yards in each of the first six games of the season, has allowed 229 (Seattle), 301 (Buffalo) and 295 (Indianapolis) in the last three games. The Jaguars currently rank 21st in the NFL in total defense. "We've adapted our defense to our personnel," Meyer said. "We've simplified things and the last four weeks they're really playing as well as anybody in the NFL. The strategic part of it, there are notable differences – but I think mindset as well."
