John shared this sneak peek
His picture suggests the 118 are about to be thrown straight into the deep end in the first few episodes, although it's unclear if he sustains the injuries on the job or an accident.
Following the lives of Los Angeles first responders, the series is now filming it's fifth season and follows Captain Bobby Nash, played by Peter Krause and the 118 - Buck, Eddie Diaz, (Ryan Guzman), Hen Wilson (Aisha Hinds) and Chimney - as they respond to emergencies with the help of LAPD patrol sergeant Athena Grant (Angela Bassett), and 911 operator Maddie Buckley (Jennifer Love Hewitt).
The 118 will return for season five
Season four concluded with an hour-long episode that saw Eddie and Bobby end up in hospital, a new romance blossom, and Buck get some shocking and life-changing news.
Six million viewers tuned in to see if Eddie had died after being shot by a sniper - spoiler alert: he didn't - but the shocks didn't end there as we discovered who had been targeting the first responders and why, if Bobby and Athena's marriage was truly over, and if Maddie would ask for help as she suffers from postpartum depression.
Eddie (right) told Buck he had made him his son's legal guardian
Fans also saw Buck rekindle his romance with Taylor Kelly and was told by Eddie that he had named Buck his son Christopher's legal guardian if Eddie were to ever die.
