Premier League: Jose Mourinho says captain John Terry will receive a contract extension to stay at Chelsea beyond the end of this season.
Manager Jose Mourinho has said he can guarantee skipper John Terry "will be a Chelsea player next season".
John Terry says he is fighting to earn a new contract at Chelsea and does not see himself ever playing for another club.
Seaborne has won three and drawn one of the four matches he has played in since making the temporary move to The Valley.
The 25-year-old was forced to sit out the final match of his original loan spell, last Saturday's 2-2 draw against Brighton.
But Seaborne will get the chance to extend his unbeaten run in the Charlton team after a fresh deal was struck.
