According to Raleigh News & Observer reporter Chip Alexander, that's how long Ellis is expected to be out with a cut near his knee suffered near the end of Thursday's 4-1 loss to the New Jersey Devils.
Ellis appeared to suffer the injury during a goalmouth scramble in which several players skated through his crease. During a stoppage in play he removed his glove to check on his leg and came out with blood on his hand. He immediately skated off the ice and was replaced for the final 51 seconds by Justin Peters.
Cam Ward is already expected to miss the rest of the regular season with an MCL sprain. Peters would likely be the No. 1 goaltender until Ellis is healthy, and according to Alexander's report, Carolina general manager Jim Rutherford said John Muse of the American Hockey League's Charlotte Checkers is the first option to be recalled.
