The Jaguars placed WR Christian Kirk on the injured reserve list due to his core injury.

He’s out a minimum of four weeks.

Kirk is expected to undergo core muscle surgery and the Jaguars will be without a major part of their offense as a result.

Kirk leads Jacksonville in receiving yards (787) this season, and he also ranks first on the team among wideouts in receptions (57).

The presence of trade acquisition Calvin Ridley will help offset Kirk’s absence, though a sizeable gap exists between Ridley and Jacksonville’s next most productive wideout (Zay Jones, who has posted 186 yards on 18 catches). Tight end Evan Engram and running back Travis Etienne Jr. will be increasingly counted upon with Kirk not in the picture.

Rookie Parker Washington could also figure into the mix.

Of course, quarterback Trevor Lawrence‘s status is also up in the air after he left Monday’s game with a high ankle sprain. I'll have more on his status later this afternoon.
