Bolton's Holden backs banned Colorado Rapids midfielder Mullan
The USA international, who is out injured with a broken leg caused by a tackle by Manchester United's Jonny Evans back on March 19, feels that the 10-macth sanction imposed on Mullan is far too hefty.
Mullan broke the leg of Seattle Sounders winger Steve Zakuani in two places last Friday with a very rash challenge and Holden feels that it was very out of character by his former Houston Dynamo teammate.
"Brian is a great player who plays very hard, but he's not a dirty player," Holden said.
"I know that he never intended to cause the injury and that he feels bad about the whole situation."
