Mid-table Rovers were unable to force a breakthrough and in the end had to hang on for a point after Gillingham changed their tactics.
“I thought the first half we played very well but we didn’t take capitalise on the control and dominance we had on the game,” said Ferguson.
“Gillingham started with a three at the back as we thought they might do but then they matched us up.
“We were really dominant in the first half. The second half, they have thrown two big lads up front and gone really direct.
“It caused us a problem, we couldn’t get any rhythm to our play.”
