NRMA Insurance Broncos centre Jack Bird has had his 2019 cruelly cut short with a season-ending knee injury.

Bird was left clutching his left knee after getting caught up in a tackle during the second half of last night's win over the Sea Eagles.

Bird underwent an MRI scan late last night confirming a ruptured Anterior Cruciate Ligament (ACL).

The injury will rule Bird out for the remainder of the 2019 season, with a lengthy recover process ahead of him.

Bird will now join hooker Andrew McCullough on the sidelines after he injured his MCL at Broncos training last week.
