Chris Herd is already looking to earn himself a longer deal at Chesterfield.
The versatile 26-year-old has initially signed until January but revealed an agreement which could see his Proact stay extended to the end of the season.
Herd, who can operate in defence or midfield, strengthens the Spireites options with injuries to Angel Martinez, Sam Hird, Liam O’Neill in recent weeks.
And the former Aston Villa man has already set his sights on helping Chesterfield achieve promotion from League One, where he has played with Port Vale.
He said: “If everything goes well, then there’s something in place to go until the end of the season. Hopefully, come the end of the season, we’re on the way up to the Championship.”
Herd came through the ranks at Villa Park and remained on the Premier League club’s books until the summer, when he was released after seven years’ service.
“The club got in touch with my representatives and things seemed to work for both parties. I’m happy to get it tied up,” said Australian Herd on joining the Spireites.
“It’s a great opportunity for me with this team. I think the team is very capable of gaining promotion to the Championship and I’m glad to be part of it.
“The coaching staff seem very good and all the players seem to be on the ball. It’s an opportunity for me to get back playing and play as much as I can.”
He spent last season on loan at Championship clubs Bolton Wanderers then Wigan Athletic but his spell at the DW Stadium was cut short when he sustained a medial ligament injury.
“I’m fully fit now,” he said ahead of Chesterfield’s trip to Coventry City. “I’m at a good fitness level and hopefully I can build it up this week in training and look to kick on.
“I’m looking forward to working with Mal (Purchase) over the season. I think he’ll improve me physically and that’ll transfer on to the pitch. It’s nice to be working with someone who knows what they’re doing.”
Herd has been putting in extra gym sessions this week to get himself in contention for Saturday’s trip to the Sky Blues’ Ricoh Arena, after missing out against Colchester United.
Meanwhile, the Spireites have decided not to appeal against Drew Talbot’s red card the defender received against Colchester and he will miss the trip to Coventry through suspension.
Goalkeeper Aaron Chapman is back at Chesterfield following the completion of his loan spell at Bristol Rovers. The 25-year-old kept three clean sheets in five outings for the League Two side.
