Kevin Nolan is training with League Two side Leyton Orient.
The 33-year-old midfielder is looking for a new club after recently leaving West Ham by mutual consent.
"It is great to have such a model professional in Kevin at the club and I am more than happy for Kevin to come in and train with the squad," Orient boss Ian Hendon told the club's website.
"It is good for our players to be training with a vastly experienced and talented Premier League midfielder."
Nolan made 157 appearances for West Ham, scoring 31 goals, following his arrival from Newcastle in June 2011.
The Hammers won promotion to the top flight in his first season at Upton Park.
He left after being told he would not be guaranteed first-team football under manager Slaven Bilic.
