wide receiver has been ruled out for the remainder of Monday night's game against the New Orleans Saints after suffering a back injury during the first half.
Allen had two receptions for 29 yards and one touchdown prior to exiting.
After dealing with injuries early in his career, Allen has been a steady presence in the Chargers lineup for the past three seasons. The 28-year-old hasn't missed a game since a season-ending ACL injury in the first game of 2016.
Being able to stay on the field has allowed Allen to showcase his unique talents.
