SID Nelson could be a doubt for Tranmere Rovers going into the play-offs as he struggles with a shoulder injury.
Nelson, 23, played for the first time since March when he came on for the injured Mark Ellis in the 1-0 defeat at home to Forest Green last Friday.
The Lions defender started at League Two champions Lincoln on Monday, but was withdrawn at half-time in the 0-0 0 stalemate, which confirmed Tranmere's place in the play-offs.
Rovers manager Micky Mellon also took off Paul Mullin at the break and afterwards explained the substitutions.
He said: "They were both tactical, just to change things. Sid had hurt his shoulder, but we will see how he is tomorrow."
