Jamaica international Jobi McAnuff has reportedly been training with Blackburn Rovers ahead of a proposed transfer.
The 33-year-old has not been involved in Leyton Orient's opening two games of the League Two campaign.
It was claimed by O's boss Ian Hendon that McAnuff had been omitted due to his summer exploits at the Copa America and Gold Cup, but a move away from Brisbane Road now appears likely.
According to London24, the former Reading midfielder is currently on trial with Championship side Rovers, along with three other players.
Blackburn's ongoing transfer embargo means that, should a deal officially go through, it would have to be on a free transfer.
