Birmingham have extended midfielder Chris Burke's contract by another 12 months.

The Scotland international will remain at St Andrew's until June 30, 2014 after boss Lee Clark activated a clause in the 29-year-old's contract to ensure a further year's stay.

After joining Blues from Cardiff in July 2011, Burke has found the net 22 times in over 100 appearances and, in his debut season, helped the club to the npower Championship play-offs where they lost to Blackpool in the semi-finals.
