He was a second-round draft pick of the Jaguars last year after starring in college at Alabama. The 6-foot-6, 320-pounder started 15 games as a rookie last season, but coach Doug Marrone and teammates confirmed Monday that Robinson's season is over.
"It's a shame," Marrone said. "He's worked hard. He's a good young player, and he'll work hard to [return from the injury]. ... We're just thinking about Cam as he's working through it."
Fourth-year player Josh Wells will start in Robinson's place. He has started three games in his career, all at right tackle last season. He played relatively well Sunday for the Jaguars, who piled up 481 yards of total offense against the defending AFC champion Patriots despite the absence of injured star running back Leonard Fournette.
"It's a terrible situation. I hope we can do it justice out there for him. ... I think he'll eventually be better than ever," Wells said Monday.
Marrone said the Jaguars don't necessarily have to go out and sign another left tackle because they've cross-trained several players. Josh Walker likely will be the backup swing tackle, but Marrone said starting center Brandon Linder and starting right guard A.J. Cann also could move out to left tackle if the need arose.
"It's part of the game and it's terrible to see a guy's season end like that, especially a guy that was playing at a high level like Cam was," Linder said.
Fourth-round pick Will Richardson Jr. has worked exclusively at right tackle but the team will give him some reps at left tackle in practice as well.
"All those guys can all play out there at tackle and have played out there at times whether it be practice or a game or whether they've done it in college," Marrone said. "I feel real comfortable about where we are there. "... We're three-deep at every position in the line but what I wanted to do is just make sure everyone understands that we're not scouring [potential free agents or trades] thinking that we need to go out there and find some answers. We have the answers here in the building."
