Rangers boss Stuart McCall says he feels sorry for Gael Bigirimana, but admits he should never have been signed.
Chris Gunter will stay at Reading, after the club took up the option to extend his deal by another year.
Hannover director of sport Dirk Dufner has closed the door firmly on the sale of Mame Diouf, declaring the Senegalese striker priceless.
Interest is growing in the former Manchester United forward after he scored 12 goals for the Reds last season, but Dufner insists he will not be sold at any price.
"We are certainly not going to sell him," he told Kicker magazine. "He is definitely staying with us."
The 25-year-old still has a year left to run on his contract with the Reds and Dufner is keen on extending that deal rather than contemplating losing him on a free transfer next summer.
"Mame is happy in Hannover and we hope to reach an agreement," he said.
Diouf joined Hannover from the Red Devils in January 2012 and he has scored 18 goals in 38 appearances for them.
