Colchester United are the latest club to hand a trial to former Crewe Alexandra defender Anthony Tonkin.
The 26-year-old is looking for pastures new following his release from Gresty Road, having spent last week on trial at Championship rivals Queens Park Rangers.
The former Stockport County has also attracted interest from former club Yeovil Town, but Tonkin is keen to remain in The Championship by earning a deal with The U's.
Layer Road caretaker boss Geraint Williams took a close look at Tonkin when Colchester played non-league AFC Sudbury on Tuesday evening.
Fellow trialist in Dulwich Hamlet striker Solomon Pinnock also received a run-out with the Essex club, as they prepare for the new season next month.
