I'm playing my Liverpool save, have signed Jude Bellingham from Madrid for about 3 years. Then I accidentally find out using my in-game edtior that his injury proneness has gone up from 6 to 11? He is only 24 years old now and never have any major injuries before (his longest injury is 3 weeks from pulled calf muscle) (Image below is all injury record in his carreer which is 10 years)
I'm wondering what other factors can increase his injury proneness by 5 points (from 6 to 11) but still got no idea now.
Just checked in my previuos saves, luckily i haven't deleted them yet. His starting injury proneness is 6 and is still 6 until I sign him (in 2026). Then after first year his injury proneness increased from 6 to 9 (in 2027). And again after another year from 9 to 11 (in 2028) and remain 11 until now (2030).
