Detroit Red Wings goalie Jimmy Howard believes a left knee injury sustained at practice Wednesday isn't serious and is hoping he'll be sidelined for just 1-2 weeks.

Howard is scheduled to have an MRI on Friday morning.

"I don't think I'm that concerned about it," Howard told MLive.com Thursday. "I don't think it's going to be anything over the top where I'm going to be out a long time."

The Red Wings recalled goalie Petr Mrazek from Grand Rapids of the American Hockey League to back up Jonas Gustavsson, who starts Thursday against the Tampa Bay Lightning. Although Howard's injury could affect his chances of earning a place on the United States Olympic team, he maintains it's not a priority.

"What can you do? It is what it is," Howard said. "You do treatment and try to get back as quick as possible."

Meanwhile, defenseman Danny DeKeyser says he's not far off in his recovery from a separated left shoulder, though he won't be ready to play Saturday, when he is eligible to come off long-term injured reserve.
