Head coach Urban Meyer said Monday afternoon the team will place Arnold on injured reserve. The Jaguars (2-9) have six games remaining so there's still the possibility Arnold could return to the lineup.
Arnold was injured during Sunday's 21-14 loss to Atlanta as he was fighting for extra yards and being tackled after a 9-yard catch-and-run. That was Arnold's only target in the past two games, but before that he had led the team in targets, receptions and receiving yards since he was acquired via trade with the Carolina Panthers on Sept. 27.
Arnold has 28 catches for 324 yards in eight games with the Jaguars.
