  Neubrandenburg, Germany (Sports Network) - Sebastian Sylvester defeated Billy Lyell in the 10th round to retain his IBF middleweight belt on Saturday.

  In the 10th round, a hard right to the chin was followed with several shots to Lyell's body and head, prompting the American's corner to throw in the towel and call the fight.

  Sylvester (33-3, 16 KOs) successfully defended the belt in his first fight since winning the title in a split decision win against Giovanni Lorenzo on September 19, 2009.

  Lyell (21-7, 4 KOs) was a late replacement for Spaniard Pablo Navascues, who was suspended for failing a drug test.
