Chelsea have released midfielder Jacob Mellis.

The decision came after he admitted setting off a smoke grenade and causing a full-scale evacuation at the club's Cobham training ground, says the Daily Mail.

Mellis made his first-team debut in the Champions League last season, but was told he had no future at the club during a disciplinary hearing.

Team-mate Billy Clifford has escaped with a fine after admitting he brought the grenade into the training centre.
