Clowe (head) was placed on injured reserve Tuesday, retroactive to Nov. 6. The Devils haven't revealed the results from the test that were ran on Clowe after he sustained a head injury last Thursday, but it seems more likely than not that the winger is dealing with a concussion. If that's the case, it would mark the fourth concussion in less than two years for Clowe, perhaps making him highly susceptible to a lengthy absence. Martin Havlat was activated from injured reserve in a corresponding move.
