GREGOR Robertson will miss the rest of the season after it was confirmed he has a knee ligament injury today.
The experienced Scot limped out of Saturday's defeat against Wrexham after picking up the knock towards the closing stages of the first-half.
Paul Hurst had suspected that he had tweaked the medial ligament after the game but he has now confirmed that he will miss the play-offs and face a lengthy lay-off.
Speaking to Mariners Player, the Town boss said: "Gregor Robertson is out and I don't expect to see him in a Grimsby Town shirt again (this season). That's the biggest disappointment. Jolls (Christian Jolley) has a chance for the Aldershot game."
Christian Jolley will miss Saturday's trip to Southport with a hamstring strain. The former Newport County player did start training on Thursday but later dropped out after feeling the problem once again. But Town boss Paul Hurst is hoping that he will be ready for next week's closing game against Aldershot Town.
However, there is some good news for the Town boss after Josh Gowling came through that training session with no ill-effects. The Kidderminster Harriers loanee missed the Wrexham game with a mystery foot injury.
