Cleary suffered a compound fracture to his left foot and was stretchered off for ambulance transfer to hospital.
Crossland's direct judiciary referral Tuesday night put his availability for Newcastle's NRL grand final against Sydney Roosters in doubt.
In Sunday's preliminary final, Crossland was sent off for a hip-drop tackle on Cleary, who entered with about 15 minutes remaining.
Cleary had been benched after a stress-related bone issue in his right foot during Penrith's qualifying-final win over the Roosters; it was later confirmed as a break.
He played just 10 minutes.
It was the NRL's first send-off for a hip drop, normally punished with a sin bin.
Fans questioned whether injury severity shaped sanctions from officials and the MRC.
In April, Kodi Nikorima's hip drop fractured Penrith hooker Mitch Kenny's fibula and caused a high-grade syndesmosis injury.
Nikorima was sin-binned for 10 minutes and received a two-match suspension after an early guilty plea; an unsuccessful challenge would have added one match.
