Tonight Reds have to go again at Stourbridge and, after adding to their injury woes, it is a tough call for the Workington outfit.
Anthony Wright will probably miss the long trip to Stourbridge with an ankle problem, while Sam Smith came off against Grantham with a tight hamstring but Andrews was hoping he would be fit.
Dan Wordsworth and Jamie Mellen will come back into contention but Scott Allison will sit this game out with his hernia problem.
“It was a harsh result on Saturday,” he said. “It didn’t do us justice as I thought we were better than that, especially in the first half.
“But if we had taken our chances, we could have put the game beyond them but we left ourselves open to a questionable decision from the referee.”
Grantham picked up a controversial opening goal with 10 minutes remaining of the first half. After a foul on Scott Allison, he initially played advantage.
But, when Reds lost the ball immediately after, he did not stop play, and the visitors raced to the opposite end to score.
Joint manager Andrews admitted that, and what looked to be a clear penalty call that was denied for the home side, had an effect on the outcome of the game.
“I think he had to bring the game back,” he added. “It was a foul, everyone could see that and once he hasn’t given it, he can stop the game as Scotty was on the floor injured.
"He can stop it for him to get treatment, we were a man down trying to defend. He’s held his hand up and said he should have stopped the game but I think it was a poor decision.
"Five minutes before that, he’s missed a stonewall penalty on Steven Rigg in the box.”
Andrews paid tribute to the squad and especially some of the youngsters who were drafted in and played much of the game, after injuries forced off Sam Smith and Anthony Wright.
“Credit to the three young lads who came on for us, a 16-year-old and two 17-year-olds who came on and did a decent jobs for us,” added Andrews.
