Sky Sports understands former Bolton defender Paul Robinson is training with Nottingham Forest.
Robinson is a free agent after being released by the Trotters at the end of last season following the club's relegation from the Premier League.
The 33-year-old left-back is believed to be training at Forest with a view to a permanent move despite the upheaval at the club.
Steve Cotterill was sacked as manager on Thursday following the takeover of the club by the Al-Hasawi family and reports have linked a number of bosses with the vacant role.
Robinson has vast experience having played more than 200 league games for each of Watford and West Brom before moving to Bolton.
