premise: Ben Marshall (born 8 June 1990) is a retired rugby union player from Ireland. He primarily played as a lock or in the back row. Marshall played for Irish provincial sides Leinster and Connacht in the Pro12, but was forced to retire in 2017 due to a concussion injury.
hypothesis: Ben Marshall is rugby player by injury.
reason: This statement is neither true or false because there is no evidence that shows Ben Marshall is a rugby player as a result of any injury. We don't really know why he is a rugby player.
