Jacksonville Jaguars LB Myles Jack won't play against Miami Dolphins because of back injury

Jacksonville Jaguars linebacker Myles Jack will not accompany the team to London for Sunday's game against Miami because of a back injury.

Jack was hurt during last Sunday's 37-19 loss to Tennessee and did not practice this week. The Jaguars (0-5) leave for London on Thursday evening. They will play the Dolphins (1-4) at Tottenham Hotspur Stadium at 9:30 a.m. ET.

Jack has started all five games this season and is the Jaguars' leading tackler (36). This will be just the eighth game he has missed in his six-year career. Dakota Allen likely will take Jack's spot at weakside linebacker.

The Jaguars have lost 20 consecutive games dating back to a victory over Indianapolis in the 2020 season opener.
