The former Melbourne midfielder is understood to have suffered a knee injury late last week and missed the Eagles opening NAB Cup games in Perth last weekend.
Morton, 23, had been listed to make his first appearances with West Coast in the triangular NAB engagements with Geelong and Fremantle in Perth, but did not play.
He is expected to have scans and further medical assessment early this week to determine extent of his injury.
Early indications are that the potentially high-flying, loping midfielder and handy forward has tweaked a knee cartilage.
The one-time highly regarded number four pick from the 207 national draft crossed to West Coast through last year’s trade period after Morton managed just 33 games in the past three seasons at the Demons.
He managed 73 games at Melbourne overall, but only nine appearances last season operating predominantly as a winger and sweeping defender to average more than 16 possessions a game at the elite level and played most of 2012 in the Demons VFL affiliate club.
Morton will contest for a berth in West Coast’s highly efficient small and crumbing forward battery or even for a spot on a wing.
He crossed to West Coast with other hopeful forward and centreline candidates Sharrod Wellingham and Jamie Cripps.
West Coast also has champion forward sharp-shooter Mark LeCras and experienced goal-shark Mark Nicoski back into their selection frames for this season after they missed the entire 2012 season with serious injury.
Morton is also up against the likes of other handy opportunist forwards Josh Hill, who bagged 36 goals from 22 outings last season, Ashton Hams, Brad Dick who is also recovering from significant injury woes as well as Wellingham and Cripps who offer West Coast similar versatile forward and midfield credentials to the former Demon.
