The Nigeria international was a handed a three-match ban after he needlessly kicked an opponent during a recent clash with Fulham but is set to return on Saturday
The Nigeria international was dismissed for kicking out at Sascha Riether during his side's 3-0 defeat to the Cottagers, earning himself a three-match ban in the process.
However, Keen claimed that there are no hard feelings towards last season's top scorer and revealed that Odemwingie has been working extra hard in training during his suspension.
"I think since I've come in and met Peter I can tell he is a really good guy," the coach told the Baggies' official website.

"I would say his training over the last two weeks is as good as it's been. He's got a fantastic quality, whether it's passing and moving or his finishing.
"His qualities are really, really top-drawer. I've been so impressed by him in general - and certainly over the last two weeks.
"He's chomping at the bit to get back into the team, and perhaps to make up for his sending-off, and give the lads back a little bit after feeling that he maybe let them down at Fulham."
Keen also suggested that Odemwingie's sending-off will not be held against him when Steve Clarke picks the team on Saturday.
"Again, his training has been fantastic over the last two weeks and he will certainly be in Steve's thoughts for Saturday," he continued.
"He's a great player, whether starting or coming off the bench. He's got some real quality and a goal in him every time he goes on the pitch."
