CROWS utility Luke Jericho is likely to miss the next three games after scans revealed he has a cracked sternum.

Jericho was on the receiving end of a heavy bump from Port Adelaide ruckman Dean Brogan in the second quarter of Sunday night's Showdown and spent considerable time on the bench before returning late in the game.

Jericho is the second Adelaide casualty from the brutal clash with the Power with defender Kris Massie also likely to miss this week with a hamstring injury.

Nathan Bassett (concussion), Jon Griffin (heavy knock) and Jason Porplyzia (shoulder) will continue to be monitored and should train on Thursday.
