However, Brill was named man-of-the-match on his return to the side in the 3-1 win over Shrewsbury on Saturday and has no intention of relinquishing his place.
"It has been a long time," Brill told the club's official website. "It was good to be out there.
"It has been hard, that is the nature of the position. The fact is only one person can play.
"I have to do as well as I can whenever I can and then it is up to the gaffer. To play in all 17 games until the end of the season would be the aim and hold onto the shirt."
