Hartlepool United could be without winger Andy Monkhouse for up to six weeks due to a hamstring injury.
The 33-year-old picked up the problem during the club's 4-0 League Two win over Bristol Rovers on Saturday. Scans have revealed Monkhouse has a grade two strain in his left hamstring, which normally requires four to six weeks in the treatment room.
Manager Colin Cooper said: "It's disappointing news because Andy has played a lot of games for us this season in a few different positions as well.
He added: "It presents an opportunity for someone, if not Jack [Compton] then one of the other players who think they can have an impact in that position."
Monkhouse has scored five goals in 34 league appearances for Hartlepool this season.
Middlesbrough football club has appointed Craig Hignett as assistant head coach to Aitor Karanka.
Hignett has left his position at Hartlepool United, where he has been doing the same job for Colin Cooper.
He returns to Middlesbrough, a team he once played for, just ten months after he left his post as a youth coach at the club. During his career, he made 194 appearances for Boro - scoring 48 goals.
Hartlepool United boss Colin Cooper is hoping to keep the pressure on the teams above his side in League Two with a victory over Southend tonight.
Hartlepool have bolstered their squad with the loan signings of Jack Barmby and Luke Williams.
Midfielder Barmby, who is the offspring of the former England forward Nick, arrives from Manchester United, whereas Williams has made the shorter move from Middlesbrough.
Hartlepool United have confirmed that striker Steve Howard has left the club by mutual consent.
The 37-year-old had fallen out of favour under Colin Cooper this season and his contract was due to expire at the end of the current campaign. The club has now reached an agreement with Howard that brings his second spell at Victoria Park to an end.
The club has said the agreement will reduce its costs and help them adhere to the Football League Salary Capping requirements. Pools added that it allows flexibility for recruiting loan players should they be needed.
Howard first joined Hartlepool in 1995 and spent four years with the club until he left for Northampton Town in 1999. He then rejoined Pools as a free agent in 2012 after being released by Leicester City.

Hartlepool United boss Colin Cooper says he's hoping to follow up last weekend's draw at Bristol Rovers with another good result when Pools host Oxford United on Saturday.
Former Hartlepool United veteran Ritchie Humphreys has been elected as the new Chairman of the Professional Footballers' Association.
The 35-year-old, who spent 12 years with Pools from 2001 to 2013, succeeds Clarke Carlisle in the role after being chosen by the PFA's Management Committee.
Humphrey's told the organisation's official website: "I am fully committed to the role that the PFA plays across all areas of football and will make every effort to continue the great work which Clarke has put in during his time as Chairman.”
Hartlepool United manager Colin Cooper says he could still add to his squad before the end of the current transfer window.
Among the new arrivals is defender Christian Burgess, who has joined on loan from Middlesbrough. Striker Nialle Rodney has also arrived at Victoria Park as a free agent. But Cooper says he's still looking at potential signings.
