Neil Aspin says he had to act after making three new signings on deadline day.
The Town boss was kept busy with deals for three loan players after the capture of James Knowles from Bradford Park Avenue earlier in the week.
Defenders James Bolton and Adam Jackson both joined the club on loan from Macclesfield and Middlesborough respectively.
Fellow defender Matt Pearson will be heading in the opposite direction though after Monday’s game at Bradford Park Avenue, with parent club Rochdale recalling the tough-tackling centre-back following his impressive loan spell at the Shay.
Alex Titchiner’s loan from Fleetwood also expires before a possible play-off campaign at the end of the season.
Aspin said he had to bring in more bodies after finding out about Pearson’s recall, which left him two defenders light following the news that Liam Hogan’s medial ligament injury may keep him out for the rest of the season.
The Town chief said: “We’re faced with having to play a quarter of our season in a month so we didn’t have enough players.
“With Alex Titchiner and Matt Pearson going back to their clubs we were in a bad position.
“It’s a shame to lose Matt but it’s a shame to lose Liam Hogan to injury as well.
“It was important that we knew Rochdale were recalling him in good time because there would have been nothing I could have done after the deadline.”
Another addition was striker Danny Glover, on loan from fellow Conference North side Worcester.
Glover’s dad Dean is a former teammate of Aspin’s at Port Vale, and the Town boss says he’s monitored Danny’s progress since his days at Vale Park.
He said: “I know him well and I’ve kept an eye on him as he came through the ranks at Port Vale.
“He played against us twice last season against Nuneaton as well. I’m delighted to get someone with his experience and he’ll be a good addition.”
