MARCUS Marshall is the only doubt going into Saturday's Vanarama National league clash with Aldershot Town at Blundell Park (3pm).
The Town midfielder pulled is back in the warm-up ahead of Tuesday's reserves game at Notts County and was forced to sit out training today (Thursday). Now the 25-year-old, who has only recently returned to the squad after missing the opening four games of the season, could face a fitness test on Friday.
Josh Sunter (foot) and Scott Brown (ankle) are both missing with injuries.
Josh Gowling will serve his third game of a three match ban against the Shots.
The thoughts of boss Paul Hurst are coming up very soon on Mariners PlayerHD.
